Fender super 210 volume pot/bright switch

[Locrian99]

I recently acquired this super 210 for basically nothing.   Everything is working other than the clean channel volume pot/switch was replaced with wrong value and the volume pot does nothing.   The switch tracks are all destroyed as well. 

Currently clean channel works but its always at max volume.   Of course the awful dirt channel doesnt.

Pcb pad for pin 1 of volume pot was destroyed so i just wired that to where it was going, checked continuity with ground when dirt channel is off and its good.   The bright pads are all destroyed and i can live without it.   But is it somehow causing the volume pot not to work?   Even with the 500k volume pot i would think it woukd still effect volume.   

Is it possible to remove the vactrol switching and eliminate the dirt channel and just wire it up like a normal volume pot.   And would i then jumper r108?   

Other thought is just rip the pcbs out and try and do like a bassman or bandmaster eyelet board in there reusing the chassis/cab and xformers.
Which i may end up doing either way.

Not easy amp to work on.

R108 you are talking about. It should stay there.

Not enough information to say what the problem is from what you have said so far, but my hunch is one or several bad traces or jumpers. If you keep mucking around trying to find and fix the broken stuff, chances are you’ll break more stuff. Those cheap PCBs are only really designed to outlast the manufacturers warranty, and it’s likely past its use by date which is why it was dirt cheap. If it were my amp, I’d gut everything, keep the iron and the tubes, and rebuild from scratch.

Yea thats i was leaning towards.    Just reusing the xformers and possibly rhe chassis/cab.   Though the cab is junk too really.   Thx i just needed affirmation on not worth it :)

It had one of those blue frame alnico eminence speakers in it and cost me a pedal i made as a trade.   Only reason i grabbed it so im happy.   Just figured id poke around and figure it out if it wasnt too much hassle.
