Pulled the chassis, blew it out, cleaned the pots, jacks, switches and tube sockets. Thought I'd share some pics. She's much purdier now.
I noticed a couple of things that could be normal, or might be signs of old age.
1. The loop selector switch pops when going from loop off to loop on and back. Only happens when adding or removing the loop and master volume, not when turning the effects loop on/off while the master volume is still in use.
2. The loop master volume on front is a lil noisy when adjusting it.
3. The presence knob on the orange channel doesn’t do a whole lot when set to modern mode.
Oh, and one of the EL34s doesn't have the plastic key part that inserts into the socket.
Haven't decided if I'm going to keep it.
If I did keep it, I'd probably update the power tubes with new 6L6s. The ehx 12ax7s (square getter China in V2) sound good, but I'd still roll some for fun.
