   It sounds like you need to make sure all your switch & relay contacts are   
   clean. I use deoxit for this kind of thing.   
      
   BUT: As with any tube-driven electronics, it's REALLY important to make sure   
   you replace all the old electrolytic caps before powering it up. If one of   
   them fails and shorts, they can burn out a transformer (which can be REALLY   
   hard to find). So, I'd    
   take care of those first.   
      
   Second, look for and replace any selenium rectifiers you find in the power   
   supply (they look like stacks of 1-inch square plates). If these fail, they   
   can catch fire.   
      
   FWIW: I don't power on a tube unit until these last two steps are done.   
      
   Good luck!
