I am no expert on electronics but I can think of 3 things you should do:
1. Take the grills off of the LaScalas and look for torn or decayed surrounds.
2. Get permission to pop the covers off the electronics and look for bulging or leaking capacitors that will have to be replaced. If there are none and you make a deal, proceed to step 3.
3. Bring the voltage up very gradually on electronics using a variac.
