My jcm800 seems to have shit itself!!

Will give this guide a whirl and see what happens! Not to bad at soldering and can read a schematic....so if changing a few tubes doesnt work, i might open it up and have a look around. Just try not to do too much damage heh. And i am an electrician, so i know all about electrical safety

does anyone know of a similar place in NJ or NY that offer this kind of service (tube tester, etc.)

I hate to say "When I was a kid!" But when I was a kid, the local drug store had one in it... And they sold some tubes! It's like, I don't know, people don't have tube driven electronics anymore or something!

I'm glad there are a lot of guitar players pursuing technique as diligently as they possibly can, it leaves this whole other area open to people like me.
