Ah, those crackling Jolidas!!!:^)
I want to say that Rives is probably right on his second guess... I just want to add that it could be a coupling capacitor(s) that don't have a good DC isolation anymore.
Most-likely it's possible to replace all coupling capacitors with better more reliable versions and better sounding that you should inquire for more.
