RE: Fisher Amplifier Voltages Questions

Ok, did some cleaning up of the rectifier socket and now I'm getting 6.8VAC across the filaments of all the tubes. Did some monitoring upon power-up and I'm getting 405VDC intially but starts to drop down to 369VDC and holds steady at this voltage. Getting red plating now on one of the EL84's. I'll check the grounds to the chassis next. This is a fun one...not really. There is some lamination splitting on the power tranny too. Is there an easy way to test it and fix it. I have some options here. Keep for complete rebuild or return it for a full refund.
