how about Stereo60? Is it using some parts that is impossible to find nowadays?
-------------------------------------------

Standees Resistors will be difficult to find : )


The cathode resistors and power supply filtering resistor commonly fail in the Stereo 50 (this may be induced by leaky coupling capacitors on the output stage). These resistors are no longer available, and often replacements may have been fitted to the amplifier below the chassis, or shoe-horned into position in an unsatisfactory way above the chassis

See the Standee resistors
My Stereo 60 did not open voice.

""One time shoot - get a leak 12.1 la...HAHAHA"" X2, X2

Simply, (but more) reasons
Those miniature X7, EF86 are really far not the match of EF37a and ECC33 used in TL12.1

Their transformers are much downgraded when compare with TL12.1 double bobin symatrical Partridge.

TL12.1 Monobloc design give you double headroom on PSU.

low uF fast sound PIO box cap v.s. cheap electrolytics

With VT75, a TL12.1 sounds....really transparent and presence

William,

Not have seen you for ages! What course of study you are doing? How is your audio system?

最左邊那隻 Partridge WWFB 系列 output,是這套重料Williamson KT66 的靈魂。Double bobbins,初級 10-12K,次級 8 組獨立,看不到是 0.95 、 1.7 抑或 3.6。

古董廠機,其 output 次級如果是有 4 組獨立的話,大致上已可斷言是頂磅級數。用到 8 組獨立,自然是超越頂磅級數的了。

8 layers in secondary - I guess this can be tape to 32 ohm for some old speakers.

It is a mono amp, cannot enjoy the stereo sound!

-------------------------------------------------



如果次級每組為 3.6 的話,便可接成 3 x 3 x 3.6 = 32.4 了。

不過,我估計次級是 0.95 或 1.7 居多。

電源供應陣容確是異常龐大,古董廠機極少見。

可惜,夾到一對屬高難度動作。

William,

It is not a business at the present stage. We are still in the R&D stage. Hopefully we can have it launched by early next year. We shall aim at the overseas market. We don't think clever HK guys will be brave enough to spend $25K to buy our preamp, though they will pay over $250K to buy a foreign branded preamp.

So my office/workshop is more like an extension of my home with a place for storage of my amps and the components for making the 27M preamps.

Give me a call tomorrow and let's chat. I think I lost your phone no. :)

Regards,
Richard
