Default Krell KSA 50

Hi

If the KSA50 clone building proceeds I also like be be part of this building project.

I have a KSA100 which I still like very much so dont be put off by the fact that it possibly is a "old design".

Hello to all, my wery first post on this forum...anyway, regarding to this subject, i found this schematic:

http://digilander.libero.it/hienddgl...li%20Krell.zip

It might be useful. I also was considering cloning this old beast (NOT my first project, more around 20-th), but where to get theese 2N6421, 2N6433, 2N6538 transistors, or what replacements to use?

Regards,
Zoran

I KSA 50 it is 100 nF, but in MK2 it seems to be electrolit. I se error on schematic of MK2. For sure should be conection beetwen collector TR8 and base TR10, and collector TR7and base TR11. What You think?

regards
bogdan

Hi,
I didn't draw this schematic, but got it from Bogdan

I've also nitised the missing C to B connections in the driver stage.

Normally the cap across the bias transistor are below 100nF, so what are we going for???
