Does anyone have,or know who has, info, maybe calibration instructions for this beast? I just finished installing brand-new ceramic sockets everywhere I could on this beast. My usual cal procedure produces ambiguous results!
Somebody has replaced the line adj pot (not the line adj control, but the smaller calibration one on a tag board with the rest of the cal pots), and I'm not sure they got it right. You know how I could tell it had been replaced? Pan-code tags on the wiring! :lol:
But the line adj and the line control are working in tandem, and the result goes around and round in a circle. :?

Hi Steve,

I've got the manual and schematic. I've never seen any specific calibration instructions for the 752A. I've read where you can extrapolate the calibration procedure for the TV-7 to work but I've not tried it on my 752.

PM me your email if you want the manual and/or schematic.
