Unhappy Radford Ldo3 not oscillating

hi, I am looking for any information on the stabilization control board, (M3366/2), fitted on the main oscillator PCB (M3363/4) in the Radford LDO3 oscillator.
My LDO3 has stopped oscillating and I suspect this control board but I cannot find any information on it.
A diagram or parts list would be very helpfull as I already have one for the main oscillator board, but any information or ideas would be most welcome.

Stan Curtis made the 13 page LDO3 technical manual available on

If you have anything on this model which is not in that document, I would appreciate a copy.
