Bendix 0526 AA5 Problem
#1

I'm looking for help with my Bendix 0526 AA5 restore. I replaced all the electrolytic and paper caps, speaker and all 5 tubes. I've been through the alignment several times monitoring the AVC line but all I get is very strong stations and the audio is garbled, sounds like it is detuned. The station at 1500 is somewhere down around 700. My freq monitor says the LO is running very low so I swapped out a resistor and 47pf cap with a small improvement in LO freq. Here is the schematic:

Any ideas?
