Hi, LT rails all fine.
With regards to plug in voltages, I take it we start at contacts of J1. If I have read my schematic correctly, pin 16 should have power, but actually has no voltage that I can measure. I verified my counting on the pins by reading pin 27, which should be -100V, which reads correctly on my machine.
Does anyone follow me there? I can post a snippet of schematic if necessary. Hoping its just a duff wire on pin 16.
Cheers from Bill.
