I don't have the amp, but i've got the service manual. If you give me a valid email address with enough room for about 2.6Mb, then it will come your way.
Best regards
Ebbe

hi,
i have a question with the input impedance of the preamp and the input cap it is 100nf then 1M resistor to ground then going to the fet transistor 2sk170.
can i chane the cap to 10uf and the resistor to 100k?
why is the 1M resistor there instead of 47-100k?
can somebody explain it to me please?

Hi namcir,
The J-FET input is much like a vacuum tube, or valve. It doesn't require a low resistance to ground for bias currents. Therefore they can use a smaller, higher quality capacitor at a higher resistance and not sacrifice bass response.

I'd leave it the way it is. Going to an electrolytic cap is a step backwards in quality. Sounds like it has promise as a good amp.

hi,
thanks marvin, oh yes now i know...
this is a good amp IMHO better than my yamaha amp more detailed and good in midbass.
but i think there are things that can be improved.
for the preamp input cap i'm planning to substitute it with a 10uf mkt not an electrolytic.
i have noticed there are some differences in the sm example in the preamp sm indicates 2sk363 input fet but actually in the unit they used 2sk170. again in amp driver stage sm=2sd669,2sb649
but amp=2sc5171, 2sa1930 and some parts etc.
i dont know why? can somebody explain? is the one i have a new version or an old version? ???
anyone?
