You're probably correct in assuming the XLR's are inputs...the only other
early mike connectors are screw-on connectors which resemble coax
hut seem to be equivalent to 1/4" phone connectors.
As far as components...I was thinking of tubes, as well as high-voltage
electrolytics. These often require replacement, and usually can't be
found at your local electronics emporium!
Hint: try music stores that repair guitar amps...those are often vacuum
tube devices running push-pull 6L6 power amplifiers...
