Well I adjusted r212 and no extra modulation. I am wondering if the amc circuit is faulty. I put my ohm meter across the vr14 pot and when adjusting it I noticed the value didn't vary much at all. The potentiometer has a 102 stamped in it. What is it suppose to be a 10,20k. If so should I notice an appreciable difference in value as I adjust it. When I put it on the pots for vr13 or vr16 it did move considerably in value. Should I try cutting out the AMC circuit completely? If so what do I need to cut in order to do this(diode or resistor and location)? Thanks for any help.
