I have sawtooth wave at the gate pads on the output mosfets for the first 3-5seconds when i turn on the amplifier. Then the protection circuit kicks in and amp goes into protect.
No matter if i plug in RCAs with sinewave or not, the same.
I also suspect 2SC4672 + 2SA1797, they get warm but read fine on the MM.
Q11 + Q7 also read fine on the MM, but i know they often fail. I've even tested the last two on the transistor tester - they've showed HFE~40.
The IC's which are glued if i'm being correct are lm211 + tl072c
