okay, i just bought a used 5150 and i noticed when its moved around it sounds like a spring or something falling. i don't know if this is common in tube amps or what, can somone fill me in on what it could be
Sounds like your reverb pan shifting. Its supposed to be somewhat loose and it has springs inside. If everything works your ok.
well, i dont know is there alot of reverb on the 5150? because i was turning it up and down and it didn't really seem like a difference
Check and make sure your wires are still connected to the reverb pan. Unplug them and plug them in again. Check for broken or frayed wires.
uhm, i don't think i know how to do that. or think i should try in that matter
