I just picked up a used Mark IV - 2002 vintage. I'm having problems with the reverb --> sometimes it's on 100% working while other times, nothing. Here's what I have tried:
- plugged/unplugged & jiggled the connecting jacks
- removed and unwrapped the tank, visually checked the
connections/solder joints
- checked the rear pot (all connected)
- made sure all the tubes were fully in/seated properly
- made sure that all tubes were lit.
All other functions work fine.
Does this sound familiar to anyone? What should I do next? Time to take it to the shop? FWIW, I was thinking about doing a full retube, but before I do this, I would like to fix this problem first (unless there is a connection between it and retubing).
Thanks to everyone for their help! :?:
