Find a good shop, and be prepared for a bare minimum of a total retube and having the filter capacitors replaced, I can't see or hear the amp, so it's hard to say whats bad, or what kind of shape it's in, but I wouldn't hesitate to put some money in it, once it's fixed you'll have a very powerful amp, Have you had this amp long, or did you just pick it up? What kind of money do you have in it?.....
