I had a problem like that . Replaced alc pot and power adjustment pot .
Sometimes they just might be dirty . .Then retune board . It didn’t play nice
in adjustment but little over 90+ watts it was rock sold . 100 watts sometimes
would jump to 130-140 watts so I ran it at little over 90 watts.
I almost always ran 30 watts as that’s all amp needed .

Good day list.
Kindly have a look at the 30' video and notice what happens as I increase
output power.

Power supply plenty strong, fuse OK, A9 board capacitors replaced.
Thanks for any wisdom.
