by high impedance I mean that a wire is likely broken off leading to a
gate input in the logic resulting in an active state...
Check you wiring and operation of the logic...

Scott,
I am sorry that it is necessary for you to repeat things to me. My
memory has improved, but still has holes in it. For some reason, I
keep re-solving the problems instead of remembering the correct
answers. Please bear with me, and I am sure that you will be able to
guide me to a working amp at 1W ierp. I just hope it happens before I
drive you nuts.
Ok... first, I need to get your amp going and get the new problem
worked out of the overcurrent circuit. The newly wound output
transformer did not get a chance to transmit today. The transmitter
was powered up by first turning on the 5 and 12 Volt auxiliary
supplies, and the LED immediately came on, so the FET supply was left
off until I can find out what is wrong there and fix it.
You mentioned that noise could be causing the overcurrent circuit to
act up. Should I try putting bypass capacitors to ground on the 5 and
12 Volt inputs? This may reduce possible noise from the power supply
lines.
When the amp works into the dummy, the tap is adjusted for 100 Watts
output, or else I drag out a blanket with which to make smoke signals.
Thanks...
J.
