I am not sure where the AGC line is in this radio...............I ordered
the service manual for this radio from ESSO last Friday.
The S-Meter is functioning, but still, I realize that this doesn't tell the
whole story. I am expecting to see a shorted AGC timing capacitor.
Once I get the schematic, it will be a little bit easier to muddle through
the circuit. For the time being, I am stuck.

If anybody has seen this problem............I picked up a couple of these
radios from the local airport. Two of them work ok, but the other two are
running open loop with their gain. In other words, no AGC. Any ideas on
what
could be causing this?

Either the front end is not getting proper AGC voltage, or the detector
stage isn't producing it. What do you measure on the AGC line, and does
it change when you tune stations in and out?
