I just have a few questions regarding buying a used amp.

I might be able to buy a "hardly used, excellent condition" Traynor YCV40 Custom 212 for 350, and I was wondering. If this deal does go as far as me getting there and checking out the amp/buying it, what are some things I should look for conditionwise? Anything to do with like.. the transformers or the tubes? Help please :/
First off, that is one sexy deal for a very nice amp. Play it and try to crank it a little to see if the tubes work and all the wiring is fine. You will be able to hear if something is wrong. If you play through it for a good while and hear nothing wrong, CONGRATULATIONS. You will have a very nice amp on your hands.
