No source or load applied as yet. I just wanted to check for operation minus smoke. I will set the bias and see if there is sound.
Here is a pictorial of the amp. If anyone can ID the board I would appreciate it. The PO had no information on it.

Yes. This is factory wired. All rivets where they are supposed to be and model designation of 70A on the front apron of the chassis. This leaves me in a quandary. The tube sockets need to be replaced; but I don't want to alter the factory wired look. Has anyone replaced the terminals in the existing sockets? Is it even possible?

Set the bias from 2.7 left and 3.1 right, to 1.5 each and cranked her up. Got a little power switch noise and hiss. Then a most pleasant sound came from those junky old speakers. Heaven!
Thanks for the suggestion. I really appreciate all input. Lots to learn.
