Hi Lou,
It's normal for some leakage in germanium transistors. Do you have a
curve tracer?
If you change them to Si you will have to re-bias them (i.e. R207_8).
The 84 Hz may change also, might have to adjust C203.
But should be possible.

Thanks for the info. It is in keeping with the original design.
My 845AB 15v supplies are currently down and I suspect the germanium
transistors around T202 may be leaky?.
Am thinking of replacing them with Si transistors. Your thoughts?
Regards, Lou

Hi Lou,
Its been awhile since I made this mod, but I had the foresight to save the
project to K04BB's site.

Still works great, hope you have the same results.
