[Central-Electronics] Whew!

[K3PID]

I was sure I did a good job of replacing the Caps and cleaning it up but
when I powered up the 20A the relay would not drop out. After checking the
audio amp and the audio rectifier I couldn't find anything wrong except that
the 12AT7 (c) was in conduction all the time because the bias voltage was
way low. After removing components one at a time to find the cause, I
finally found that the 12 KOhm coil on the relay had 50K to ground...... It
measured 12K OK but the coil read 50K to ground so it was pulling way to
much current thru the supply resistor. Turned out to be a short in the fiber
insulator that separated the finger that fed the coil from the frame....
whew! Works fine now! Now I can get on with the rest of the circuit....
Maybe I'll get it on the air this weekend!
