...in one of my amps and have new values to post in the schematic. For example, the main-supply rail is 524VDC, not 590, and the 'EM7 rail is 292 and not 345. Voltages on the plates are (left to right) 161, 253, and 502. I'll give all these to my buddy and get and post a new schematic soon. Sorry for the confusion. Might he have measured it without tubes loading the supplies?
I'm still confused/fascinated with the main supply. FWIW, DC Voltages in that supply, left to right, are 547 on the 5U4G plates, 535 at the cathodes, and 527 after the choke and caps. My 'guru' (who is NOT the 'schematicist') thinks there's possibly too much capacitance at the output.
And this clearly illustrates my low level of knowledge in these areas; I'm definitely at the little-knowledge-is-dangerous stage.
