In the midst of re-building a Marantz 1060 (new caps, trannys, whatever else is required), my phono input went dead.
Context: The phono board had been passing signal on one channel; new electrolytics, transistors, and output caps brought me up to two channels, but I'd goofed up and installed wrong-sized output caps, which filtered out most of the audible signal. Upon replacing the caps: nothing.Using an audio probe, I've established the signal goes kaput on both channels right around H901/902.
I suspect it's a power-supply issue, but I've been unable to sort out what's going on in the selector switch with its various settings.
Question: Can one of you kind folks lemme know if the following DC voltage readings are where they should be?
With selector switch in PHONO position:
J912 = 1
J914 = 36.3
J916 = 1
J913 = 1
J915 = 36.1
J917 = 1
J 904 = 41.5
Selector switch in MIC position
J912 = 7
J914 = 7
J916 = 29.7
J913 = 7.1
J915 = 7.1
J917 = 30.8
J 904 = 41
Much obliged!
