    Per chance, does anyone have a copy of the aforementioned SM? In the absence of one, I can obtain a manual for a 7055, or a 7065A. Which of the two is a closer match? Thanks in advance.

    Manual for 7055 would be the better choice.

    Found a manual and the receiver found its chi. :D R&R ALL electrolytics, R&R diodes in PS, R&R all transistors on PS/power amp board, Deoxit switches and pots, new lamps, new fuses, refinished wood case (though it does have some imperfections), and cleaned up metal. 13mv L and 14mv R channel DC offset, and 50mv DC Bias both channels. No adjustments for DC offset so I'll take these results! Breaking it back in with some Steely Dan and it appears to be happy. So am I. :thumbsup:
