Nice one so far.... I like the covert pots in the front tube sockets.
But back to poasts 13 and 14 re your bias supply....

And is that really still the selinium rectifier I see in there or have you tucked a 1N4007 away out of sight across it's contacts?

Having been requested upon restoration of my newly restored Dynaco Dynakit ST70 Amplifier, I've decided to test out the Amp by directly connecting the Commodore to it, and attenuating the signal instead of using a pre-amp. A visual output of the signal will further be my restored 1950's Heathkit laboratory oscilloscope. After setting the volume I just roll right into the demo songs. Enjoy.
