Will build the Nishiki amp with 2sc5200.
Will order from Mouser.
Is it any diffrent in this parts? Can i use either?
2SC5200 STMicroelectronics Bipolar Power
2SC5200-O(Q) Toshiba Bipolar Power
Thanks //Daniel

Hi
The last time I got in touch with Toshiba Electronics Asia, I was inquiring about Fairchild's 2SC5200 if it is at par with their Toshiba 2SC5200 this is their response,
Thank you for your inquiry.
Toshiba has replacement part for 2SC5200/2SA1943.
Replacement part nos. TTC5200/TTA1943.
you may consider this pair,
Pls open this link to view the data spec,

Seems like STmicroelectronics did also produce their own 2SC5200 huh

aha, ok, i have just seen one lockated here:
http://www.wimdehaan.nl/downloads/technicalmanualnishiki41.pdf
I will go for a ecc88 in front and 2sc5200 for the output. +/- 25V

Distortion gets a bad rap. This is harmonic coloration, of the type much valued with tube amps for guitars. If you pay for the amp, I guess you have a right to express your preference!
I say the Nishiki is an interesting amp, with tube sound. The documentation is superb and ideas quite legitimate. All amplifiers distort to some degree, but THD is only part of the picture. The profile of the distortion is important. That's the reason a tube amp with 1% sounds somewhat more pure than a SS amp with 0.1% - the profile of the distortion is different, with tubes having high levels of low order artefacts and SS feedback amps having a long train of artefacts at very low amplitude.

Thanks for nice response. I am sure there is lot of hifi folks out there looking for specific coloration, so Nishiki amp will give you one flavor. Is it right to think that this amplifier is not good for complex music like rock/metal?
But isnt the crossover distortion quite high in class AB amps without NFB?
Also have you listening experience between full complementary and quasi complementary? I have read that BJT quasi doesnt work so good, but VMOS quasi does.

nishiki design
The original idea was to publish the Nishiki in 3 parts. First as published in TAA, 2nd part using a 6N3P tube in long tail with a 6N1P as cathode follower and the 3 part using an ECL82 is driver. This ECL82 does has an incredible sound. Part 2 and 3 never made it in TAA.
Enclosed a document with a Tubecad Aikido as driver, all components values are my own choice. Also, the 5965 tube does only 'sound' good when it draws at least 3 mA.

PS. the PDF file seems too large for this forum, I will try to upload it tomorrow once more with a smaller size file.

Nice to see you here, Wim. I have long admired your work.
As it happens, I'm working on a hybrid too, and just like you, have long considered the 5965 as it has ideal mu and rp for the voltage stage.
The SS buffer is done; it does use nfb, but has loop gain of around 50dB, easily manipulated.
The ideas behind it are quite similar to yours!

But i still don't understand my question in my first post. What is the diffrens between the two 5200? Can i used the cheaper one? :)[/QUOTE said:No matter the expensive or the cheap ones, price is not the judge, the real one is the answer.
we only tell the truth, nothing but the truth.
TTC/A prefix parts are genuine Toshiba, manufactured in China at lower cost. This makes it difficult for fakes of these to be profitable but if you need confirmation, download datasheets. ???? | ?? ????????&??????

Ironically, parts still marked 2SC/A will likely become suspect as fakes, as have 2SC3281/A1302.
