that's helpful info, thanks.
I do have a variac and used it to slowly bring up the voltage for the first couple hours.
And a "load lamp" which I will use as testing proceeds. Aside from the big quad cap, I have a "restore" kit from the bay with a number of small caps and components.
I will not do the voltage tests described in the tuner manual though. Not going to mess with 400+ volts. I have to put a kid through college the next few years so I can't take the risk of doing something stupid yet...
