Finally getting back to this old amp. 1940 Gibson EH-? Replacing the filter caps with same rating. The filter caps are a multi-section tubular electrolytic type (two 10/10 450), replacing with four 10uf 500VDC Sprague Atoms. The original caps have two positive lead wires and one negative wire. The positives are twisted, should I do the same? Does this cut down on noise? Then replace crumbling two-prong power cable with three-prong grounded power cable. I'll then start checking voltages. I'll need to have the speaker plugged in so I'll pull it from the cabinet to plug into the chassis while testing.

Safety ground is connected ONLY to the chassis, on a bolt/nut/star washer setup that's reserved only for this.

Standard warnings and disclaimers apply: If you don't already know how to do the AC power wiring safely, don't try it until you get in-person help and training on how to do it right.Amazing!! Who would ever have guessed that someone who villified the evil rich people would begin happily accepting their millions in speaking fees!
Oh, wait! That sounds familiar, somehow.

This point cannot be stressed enough.
There is a clear & present danger of electrocution when messing with the mains circuit.
