Yorkville repair
The MONITOR CLIP light was on all the time.
The circuit uses an MPSA13 type Darlington with a bunch of wired or diodes to the base. The base circuit trace runs all over the board. There is no real pull down for the base circuit other than the transistor input impendence which is very high. The base was being pulled high turning the light on but none of the wired or circuits were high. The base circuit trace itself had some leakage path the Vcc or something. I removed the part of the trace that runs from the transistor over to the mic input side of the board and replaced it with a jumper wire. Problem solved.
