Just picked up a 1987 JCM800 2210. It sounds decent but I want to have it checked out to make sure everything’s up to par by my tech. But before I bring him it I was wondering from anyone here who’s owned one if there’s any advice they want to give me. Do these amps hold up pretty well or is there anything that might need replacing by this point? To my knowledge the amp is original except for the tubes and a upgraded reverb tank. I’ve read that sometimes the filter caps might need replacing. I like the amp and would love to keep it for many years so just trying to get it sounding as good as it can. I might have the tubes changed also just to freshen it up so recommend me some and I’ll look into them. I’ve been told that Tung Sol 12ax7 and Tung Sol EL34B are a great choice for this amp.
