Peavey Classic Stereo 120/120

Post by hifi725 » Mon Jun 28, 2021 4:45 pm

Has anyone modified one of these for a hifi amp? Transformer places have closed their doors and everything else is back ordered. So I'm modding a Stereo 120/120. New coupling caps on order. 0.22's to replace the 0.047's 0.33 just before power tubes. The controls are horrible. Bypassing those for sure. Any input on a starting value of feedback resistor? Otherwise the plan is to use a pot and check out how the square waves look, then measure the resistance. Then resistor.

Upgrades in pic so far. IEC connector. Also an EMI filter. 5 way binding posts for more options. Highlight and copy so I don't have to type this again when it won't post.
