okay so recently I acquired an old fender bassman 100 head for next to nothing in hopes of fixing it up. I took it to a local shop that does amp repairs and was told it's not even worth repairing because of the work that needs to be done, mind you they didn't even check the head yet. The guy I bought it from told me it needed a new power transformer and retube because his sons friend left it on all night without standby so it fried so thats all I thought was wrong with it. Now im bummed because I love these old heads for both guitar and bass and I have wanted one for quite some time but now dont really know what to do about it. What do you guys think?
