Fisher made pretty nice stuff but that was a long time ago.
The power supply of the receiver employs things called filter capacitors (round cylinders near the rear of the receiver) that store energy from the power transformer. They are electro-chemical in nature, a bit like a battery but have longer lives but don't store as much energy. For sure at this point they are so old that they *all* need replacing (and they are probably all available from Antique Radio Supply in Arizona).
This will cost $200-$400 to do properly. Its important- if not replaced, they can draw excess current which could destroy the power transformer and that will likely be the end- the transformer is really expensive if you can even find one so you really don't want to allow that. Otherwise the power transformer is plenty reliable.
So get the filter capacitors replaced, deal with the tubes, get the switches and controls cleaned and then see what you think. You'll want to use speakers that are easier to drive and I would avoid 4 ohm speakers as they are far less likely to show off the good properties of the unit that made Fisher famous.
