Counterfeit Transistor, Capacitors, Hi Fi Audio, Hand phone....

I have seen a big black huge Amplifier and was brought up to the shop for checking up in Ap Liu Street, that was a Preamplifier with 19" rack, black, written on the front panel the brand name " Quintenssence". It had only one power switch and one volume, weight is about 1.5kgf!

Whilst the shop repair man opened the covers and showed to the owner of the amplfier.

I was there to witness, I saw a small piece of PCB with size of 1.5" x1.5" mounted at the centre.

The board was some kind fo FR2 low cost single layer PCB board.

A simple transformer of the size of a 8 heads-abalone.... a bridge rectifier and two smoothing capacitors of 1,000 MFD each...

I saw that there were two tiny Op-amps on the PCB, a few resistors and some capacitors, obvious that they were not those expensive high precision component. I noticed that the surface marking on the Op-Amp had been milled off, so no one who tell what kind of "Expensive Op-amp" that could be...

The problem is no sound output on one channel...

Well, at this point of view that was a" Made in USA" amplifier with HKD4,000.00 in the year of 1979....

The owner said the sound was OK....If that is OK that meaned the marketing was doing good, as If I used the same material to re-build that amplifer by myself, I think I could made it with HKD120.00!

Probbably sound the same or even better!

I did no believed that Op-amp is not a special ASIC IC at that time. Probably that is a hi grade LM741 Op-amp, that was about HKD15,00 a piece!

The shop owner and myself kept quiet and not to make the owner embrassed., he seemed did not know any electronics at all!

Obviously that was some kind of underground fake amplifer using the same name of the orginal. Well we can see a lot of fake hand phone, like Nokai, Sony Ericsoon, even the Aiphone. But 30 years ago some master had already been working a pro in this fake business...

Nowadays, there are fake Ferrari, Fake Transistor, Fake capacitor, fake vacuum tubes, fake transfomer, Fake LEDs, Fake maiden head! fake watches, bag, soya sauce, egg, tea, Canned Luncheon pork, coffee, almost everything... can be FAKE!

Man, take care that you wife is a man!! High possibility if she/he is not fertile!

Conclusion

We need some wisdom and knowledge to select and buy any product in the market!

A quiet Place in a Hetic City

This is a Chinese Temple amdst crowded city Sham Shui Po, actually this is just situated next block of Ap Liu Street.

Ap Liu street is a flea market place with used goods, electronics components 25 years ago, gradually they have been changed into a market for selling Hand phones, toys, Audio equipment, Video games, LEDs product, and computer related products...

In this temple, you will surprise why there is such a place in this busy place in Sham Shui Po,

The War between LP and CD...

This is an add infinitum war between CD and LP since the invention of CD in 1982...

This is a web site that has made a very scientific studies on the comparison.

Interesting to see why LP is performing better than CD in another aspect.

Comparing MP3 and CD

MP3 it cuts out a lot of audible and semi inaudible frequencies. The extent to which is does this is determined by the bitrate it has been encoded at.

I think even with 320 kbps mp3 the freq range reproduction is between 15hz and about 15,500hz or even lower than that. That's why the most noticeable differences between mp3 and CD are often in the hihats. Or at least, most people notice flatter, tinnier hihats with mp3s because the frequency response doesn't extend that far.

It loses some sub bass response too but it depends on the record and the amount of bass presence. At high levels certain bass heavy recordings just lose something noticeably when played on PAs at club levels - even at 320 kbps.

Even though you can't physically hear ultra high and low frequency sound you can sometimes notice when its not there. Case in point - have someone blow a dog whistle near you. Then there is the fact that your speakers/headphones have an effective frequency response too.

Most people don't have audio equipment sensitive enough to pick up frequencies above 15,000 Hz, so they wouldnt notice any degradation in sound quality on say most mini hifi systems.

Comparing CD with Vinyl

Plenty of people are having the same experience and are "getting into vinyl" as they put it. I get asked a lot if "vinyl is coming back" or if "tube amps are coming back" and I just inform them that they never left.

I have been listening to vinyl since 1976, that has been 32 years already. I have not changed listening to CD. Thought CD is more convenient to play, to store and to buy, but the vinyls are more enjoyable and realistic. Viinyl folder is larger, can see the lyrics, or article about the singer, player or composer, like reading a newspaper rather easier than reading a news viewer in a PDA format.

I have listened to a reasonably good system recently , that was a Goldmund CD player, pre-amp power amp driving a Khamar floor stand loudspeaker, the sound was sweet, quiet, clear and not having sharp edges, not too digital... but I was having a short while on some light music, need to confirm through vocal.


CD's tendency to have less depth and a 'flatter' bass and lower midrange dimensionality."
The trebre is a bit harsh even the best CD player as comparing with good Analogue playing sytem.

Anyway, I can say that the Vinyl lover isn't idiot as the CD lovers have such a bias on us ( a bunch of Vinyl lovers)

What should we do in this time of correction?

“The best way to predict future is to create it!”

The houses and Stock have fallen 25% and 45% respectively, from ther peak in US,

Hang Seng Index was about 27,563 in Jan 2008 and how it is around 14,000,

but I guess that it will possibly could fall further.

That is what happens when bubblies deflate- this thing can fall into a reasonable-value zone. then keep on falling until they are unreasonably low!

On the other side of inflating bubbles, during which prices can keep rising after even they're unreasonably high!

If you had the money that you won't have to use for the next 6-8 years, go and buy,

if you have to plan for your coming bill and cheque, I suggest you should do nothing!

Work hard and make sure nothing go wrong keep your job secure!

CSR

Melamine
Milk-derived ingredients include whole milk powder, non-fat milk powder, whey powder, lactose powder, and casein has been widely used on many of the food made in New Zealand, Canada, USA, Japan other than China. This milk companies including Sanlu, Menggu, had been using these uncertified milks from the milk farmers on their product carrying their Brand name. Their Top management should have no excused saying they would not know the use of such mail contained Melamine. China image has been eroded as a national wide disaster, as for the Sanlu Milk company, it went Bankrupt last week, which was not a surprise to me.

CSR
CSR, also called Corporate Social Responsibility, corporate citizenship, responsible business and corporate social opportunity. It is a concept whereby companies and organizations consider the interests of the society taking responsibility for the impact of their activities on customer, suppliers, employees, share holders, communities and other stake holder as well as the environment. This obligation is seen to extend beyond the statutory obligation to comply with legitration and sees organizations voluntarily taking further steps to improve the quality of life for employees and their families as well as for the local community and Global society at large.

The practice of CSR is subject to much debate and criticism. Proponents argue that there is a strong business case for CSR, in that corporations benefit in multiple ways by operating with a perspective broader and longer than their own immediate, short-term profits. Critics argue that CSR distracts from the fundamental economic role of businesses; others argue that it is nothing more than superficial window-dressing; still others argue that it is an attempt to preempt the role of governments as a watchdog over powerful Multinational Corporation.
CSR is a way to care and support the company, employees, customer, society locally and globally!

Typical local example of the CSR caring acts:
No Lay off
1,000 company agreed not to lay off, these company include To Heng restaurant, Sasa cosmetic, Café-de Carol…it won applause of the citizens of Hong Kong,

Our CEO has also saying that we do not have such lay off culture and we will do our best to cut 10% of our running cost in December 2008, another 10% Q1 2009, and probably 10% Q3 2009. We will like to work together to believe the target. this include energy saving, budget control and at the same time we even increase the cost of R&D… for better capture of future order when business arrives!

There are a few categories of companies.
1. Running for survival, no profit, layout is the usual practice in case of low business
2. Running with profit, cash cow of high profit margin, can maintain the running of the operation in for 3-6 months without any loan
3. Running without the support of loans for 1-2 years even without any bank loan support.

I believe that only type three companies can have full contribution in CSR as a company direction and CSR involves a large scale company direction.
Carbon Dioxide emission measurement.
We have to set a target in controlling the amount of this emission per year.

A CSR company
Build good product with emphasis on the Green value contribution to the society.

Reduces all kind of wates and CO2 emission!
Use green packing material, no or in case we can not, use less packing material.

Promotion to all employees and customer in the CSR.

Build good quality product that will not cause any harm, hazards and contaimination.

CSR is not a image building slogan, it is a department not under PR or Admin., It is a team that drive the company to contribute to the benefit of employees, customer, suppliers and clients and the peoples using our products, building the products.

Ampzilla II

Ampzilla II was one of the famous power amplifier in 1978... I had a chance to see it in Mongkok, but no chance listening to it...

You know if you asked the sale man to switch on for you; you may have to go through a series of tough questions...started with an easiler question first:

1. What kind of music you like most for testing?

2. How about "Lee Oskar"s' I remember Home (a Peasant's Symphony)?

This was the most Popular test LP in 1976, , other than this, mostly , will be Hotel California!

3. What kind of power amplifier are you using? - to understand your buying power

4. What kind of cartridge and Turntablle you wnat to buy next?- To undersatnd your taste.

5. What is your experience in loudspeaker selection? - to understand your music preference!

They were trying to probe you and see how to humilating you if you were like me, poor and dressed like a student!

At that time being a green horn for Vinyl lover, I had hard time to ask them... just wait for some tycoon or Low Ban (boss) to instruct them to... then swiftly I would move in and occupied a sweet point to listen... all I could do was to wait for such a chance...

Play That Funky Music

In 1977 Summer, Mong Kok Hi Fi shops were my best places to kill the times after my study...At that time Ai Yee, Mong Kok Fi Fi, Bo Sum, Bo Shum, Mak See were the shops that I used to visit.

(after 32 years, we still have Mak See, and Ah Yee) Mong Kok Hi Fi had closed the shop in 2007!

At that time a classmate who work on Mong Kok Hi Fi shop as a summer salesman purposely showed me his top gear in the shop.

Mclntosh MC2500 Power amplifier

JBL 16" diamater 3 ways loudspeaker

He played the Wild Cherry Music " Play that funky Music.."

It sounded like an earthquake and the music was warm, full body, musical and the bass could wack the shop...

Prices wise, I dare not look at that, as I think the C36 was HKD4,000.00

PLAY THAT FUNKY MUSICBy: Wild Cherry

Once I was a boogie singer

Playin' in a Rock 'n Roll band

I never had no problems

Burnin' down the one night stands

And everything around me

Got to start to feelin' so low

And I decided quickly

To disco down and check out the show

Yea they were dancin' and singin' and movin' to the groovin'

And just when it hit me somebody turned around and shouted
Chorus: Play that funky music white boy

Play that funky music right

Play that funky music white boy

Lay down and the boogie and play that funky music '

til you die 'til you die,

oh 'til you die

I tried to understand this,

I thought that they were out of their minds.

How could I be so foolish (how could I),

to not see I was the one behind.

But still I kept on fightin',woah,

loosin every step of the way.

I said I must go back there,

and check and see if things (are) still the same

Super Power in 1970'

Phase Linear 700

The Phase Linear 700 amplifier got its name from its combined output of 350 watts per channel. Introduced in 1970, it was, for a while, Phase Linear's only amplifier. The 700 put both Bob Carver, the amp's designer, and Phase Linear on the high end audio map.

The early 1970's were heady times for Bob Carver as he worked to expand North American distribution and beat the drum for Phase Linear. The 700 soon became a favorite of recording studio engineers (19-inches wide, it was designed for rack mounting), rock bands, jazz musicians and audiophiles.

The first generation 700 was laid out asymmetrically, with the VU meters and control knobs toward to right side of the front panel. Carver did two things with the 700 that were meant to eliminate the need for a cooling fan, lower operating temperature and aid in servicing when it became necessary: he placed both the output transistors and the power transformer outside the amplifier enclosure. The output transistors were mounted to the rear heat sinks. The 700 was 45 pounds!

The 700 listed for USD$749.00 in 1970, and rose slightly to USD$779.00 in 1972 and 1973. In 1974 it was replaced by the 700 B

Bob Carver redesigned the 700 and introduced the 700 B in 1974. It featured dual left and right channel controls. It was rated at 345 watts per channel. Rack handles were now standard. Performance specifications of the 700 B did not change measurably from the 700, but then, component improvement was not visible to the buyer and listener. List price was USD$799.00 but jumped to USD $879.00 in1977, its last year of production. It was superseded by the 700 Series Two.

The 700 Series Two was introduced in 1978 and reflected the design approach of A. P. Van Meter, Phase Linear's new design manager. More attention was paid to the 700's aesthetics; the unit was undeniably handsome. Functionally, the VU meters were replaced by red LED meters, with a single volume control under each meter. Performance included 360 watts per channel, reduced THD and IMD and other improvements.


The impressive array of output transistors and drivers is visible on this 700 Series Two with the output device covers removed. With a list price of nearly USD$900, it was half the price of some economy cars! By 1980 inflation had pushed it to USD$1000. The 700 Series Two was replaced by the completely new DRS 900, part of the Dynamic Range Series introduced in 1982.

At that time, there were Crown DC300A, Marantz 500, Mclntosh MC2500! These are the mammoths in the Hi End Audio market! I was a student and was just a dream to look into the price tags, When I entered the Hi Fi Shop, the shop keeper would like to ask what Hi Fi equipment you used as to probe on your buying power. At that time a Taksun 120Y was HKD20,000 and that Phase Linear was HKD8,000.00 half the price of a CAR!

At that time 1973 a Rolex Date Just Stainless steel and Gold two tone man's watch was just HKD4,300. Until 1982, a Rolex Stainless steel man’s watch was HKD4,200.00.

• Merrill Lynch $12.3bn
• Deutsche Bank $13bn

Honda withdrew from F1 Racing Team
Takeo Fukui, the president of Honda Motors Company Tokyo had made a statement that they would withdraw from the F1 races in December 2008. This is an action in responding to the down turn global economy situation.

Honda entered the NSX in Japan GT race just 7 years after its birth in 1990, in 1998 Honda clinched its first victory in Japan GT races.

NSX

NSX is a embodiment of Honda’s DNA since hit humble beginnings on 1985. Initially intended as a midrange, mid-engine car that provided superior performance. The creation posed one of the top biggest challenges to Honda’s engineers.

A new Vehicle that is able to balance human feeling and superior vehicle performance at high level yet required equally superior driving skills.

My NSX
I had a chance to own a NSX in 1996. That was a super car in town, tough the clutch was a bit tough from cities… but is road feeling and corners turning was superb!

They are not waiting for job in front of labour department.

They are studying the best they can as they are going to invest their time and energy in the Horse racing... GAMBLING!

It happens mostly in the horse racing season at every Wednesday/Sunday evening and on certain occassions such as Christmas, Mid-Autumn Festival and Chinese new year that The Jockey Club will arrange certain special game for them to lose their money.

Hong Kong Jockey Club annual income for 2007 is approximately HKD1,800,000,000,00.00. At least 20% will be donated to the Charity committees in Hong Kong. So that is why I said this is a losing money investment.

Why I said to lose thier money as I have never Seen a man or woman ever won in gambling! There is one of the Chinese saying " There is no Gambler to buy a land" as the lucky one will never be me.

But We have to create certain opportunity for these people most of them are from lower earning class and with less education. This is their last hope and this is their dream in such kind of bad-managed -government. Their senior offices are unebale to understand how bad the siutaion of the poor people and unable to support these lower earing class of people by porviding them jobs!

If they do not have certain channel to release their energy, they will try to make trouble to the other people and Government.

There are approximately 150,000 people addicted to Gambling and I hope that they can "Go Back to the shore" and start a new page by dropping this bad habit of gambling!

I have never gambled before, because I have already too many bad habits!

World Largest Ship

KNOCK NEVIS is the world's largest ship at 458.4 meters long (over 1/4 of a mile) and 68.9 meters wide. Previous names: 1989 Seawise Giant, 1991 Happy Giant, 2004 Jahre Viking.




KNOCK NEVIS is so huge that when fully laden she cannot pass through the 32 mile wide English channel because it cannot be manoeuvred, as travelling in a straight line is its best forte.


Fully laden, she sits 24.5 meters deep in the sea, a depth great enough to stop her from accessing most of the world’s major ports.


The cargo of oil she normally carries is worth $122 million - separated from the sea by just 3.5cm of steel plate!


The holds could swallow St Pauls Cathedral four times over. It has a crew of 35 to 40, which means it only needs two lifeboats. It takes 5.5 miles to stop with a turning circle of over 2 miles.

The Ship

The ship is proably the most economical, powerful in terms of cargo capacity, effective tool for shipment. Imagine that the containers ship can carry 5,000 containers each 40 feet long.

A 10,000 Tons General Cargo ship can be converted to carry Automobile of some what 400 Camry! A professionl car carrier or roll on roll off can carry 5,000 car in one time.

A 40,000 ton bulk carrier can ship wheat good enough for the consumption of a city like Tianjin for 6 months!

A 80,000 ton bulk carrier has an anchor with a weight of 20 tons. The main shaft of the ship is having a diamter of 1.5 metre! It burns more than 1 ton of oil in one hour! What kind of milleage is this? Comparing with your Ferrari F4 or Porche GT2?

A crude oil tanker of 100,000 tons can not be loaded in the tanks at the two extreme ends of the ship. This would cause a tragedy happened in Holland some time 1983 as the computer gone wrong and the weight of the oil that actually cracked and broke the ship into two pieces. And this was a court case for the next 5 years as the oil contamination caused Billions dollars loss to the wharf and city of Amsterdam!
