Hi everyone!

I had a general question around restoration of vintage amplifiers and receivers (specifically solid state in the instance).

Say you have a unit that is in working condition - it works as expected and is to your understanding original. If you wanted to do a restoration on the unit (aside from any model specific parts that need replacing/checking) what general pieces of work (both diagnostic and replacement) need to be done to ensure relative hassle free operation in the future. This is what I have found through my reading, can anyone suggest additional items to add to the list?

  • Replace all the electrolytic capacitors
  • Replace bulbs (possibly upgrade to LED)
  • Clean out pots and switches
  • Check DC offset and address if its an issue
  • Set Bias
