Here are 2 pictures of a Dynaco ST-70 I restored for a customer. I replaced the chassis, all the caps, a few out of tolerance resistors, bias selenium, rca jacks and speaker terminals. I replaced some wires including the line cord with a 3 wire line cord. I also took the transformers apart and gave them 2 coats of primer and 2 coats of semi-gloss paint.
He gave me 2 of them to restore...
