Another possibility is a failing filter cap.
That’s the way I’ll try tomorrow. I hope is not a failing cap :(

Considering a build, recommendations?

Re: Considering a build, recommendations?

I’ve changed just now the first v1a e v1b cathode cap 10uF with 5 uF, clean are similar and more open and OD sounds fine, less gainy but good. I’ve took a look in ODS Fuchs and I’ve found 5 uF on cathode of V1a, v1b, v2a and v2b

Re: Express oscillation solved

How bad is the oscillation? As in what control settings did it occur at? Were the bright switches on? Can you have every control in the amp on 10 with no guitar plugged in? If not then a good thing to do is to move wires around to try and stop that. Things that jump out at me are...... - The bright...
