Hello All-
Once again I'd like to tap this deep font of knowledge.
I've just completed the first alignment and test and everything
checks out except setting the AGC threshold.
When I put the probe of my DMM on pin 5 of U2 (a hellish place to get
consistent readings) and adjust R1
I get only .002 DC volts.
I've resoldered the pins on both U2 and R1. I've looked through
Troubleshooting and the Reflector and
haven't found anything relevant.
By the way I had no trouble with the S-Meter alignment which is
dependent on the AGC threshold.
Is there any place else I should look on the control board for a
possible source of trouble, or could U2 or
R1 be defective? (I know components are rarely defective).
TIA,
Jeff
