That amp is 45 years old. I wouldn't power it up until it was sent in for a full service and verified that it's performing correctly. The problem with old gear is that some of the parts may not be available anymore, like transistors. pop those or any other unavailable part and it's a paper weight.
Variac or not?
I acquired a Marantz 510M amp that had not been turned on for about 10 years. Before it went into storage it was in use weekly if not daily as the acquired couples main audio system. So my question is with this amp is it or is it not advisable to use a variac on a non tube amp like the 510M?
