If the amp is old (> 30 years) , those caps will go anyway. Nothing wrong with recapping it all.
Sudden Guitar Amp Failiure
Hey all , new here , i'll try to keep it short :Old Marshall hybrid amp, worked until I screwed up by using contact cleaner on the tube socket and didn't wait enough , switched the amp on , very loud hum with no guitar signal (around 120Hz I believe), whether the guitar's plugged in or not , turning the knobs is useless , dead LED lights.
Quickly turned it off when I noticed an unusual smell with a bit of "innocent" smoke coming from the back , near the x-former.
My guess is that the contact cleaner caused a short from the tube socket to the nearby coupling caps and overloaded the rest of them , though the fuses look fine , the tranny is obviously fine , and there are no burn marks, caps look fine but ill replace them anyway,
could it be something else?
