Picked up a Marantz Model Fifteen amplifier and 7T pre-amplifier ... I am guessing that they haven't been used for 20+ years.
The 7T powers up ... I plugged it in, hit the power switch just long enough to see the light come on and turned it off.
I am a little concerned about testing the amp ... Should I put it on a Variac (which I will have to borrow from a friend) ... and bring it back to life slowly?
