There were two minutes today when it would have been possible to figure out the SN of the donor amp for this thread....

A couple of the SSS schematics had voltages listed for the FET, which gave a clue as to the operating voltage and how HAD was biasing it. You can of course set it up as you choose, for some FET distortion or for more of a clean boost.

All the pictures from this thread were on Photobucket which won't show them.
I'll try to re-post some of them.
