Hey Mondial:
I have found the problem with the 60 and it now works perfectly. This is a strange one and I don't pretend to understand why this is but here it is. When I did the alignment I set the signal generator to the IF frequency and checked with a counter to be sure I am accurate and I set everything up and did the RF side all looked good dial wise but the overloading issue. Like you said the AVC voltage seemed low and compared to another radio it was. It seemed to me like the if alignment was out so I checked it the old fashion way, by ear tuned to a local station. 1st, 2nd, and 3rd were bang on, the forth was way off. so I put VOM on the AVC line and tuned it to the clearest reception and highest AVC voltage, -9.8 volts. All is good now.
So I went back and tried the generator method again and out to lunch again so retuned using the meter on the AVC and perfect. Any thoughts on this, using the generator method has worked on countless radios before this one.
