Hmmm,
You did not even open it up asking around all this time?, LOL!
I see similar problems when I work on solid state guitar amps
a lot. Yes, I work vintage or new vacuum tube and or SS guitar amps
for a hobby. No I am not a string player. A Life time brass player,
still playing in local concert band with euphonium marching on 74 YO.
73,
