Terry, thanks for the info. I think the osc feedback coil is OK. It measures about 5 ohms and seems stable during movement and handling of the coil. Ant coil is also OK, measured about 3 ohms. I replaced the 10k resistor (#6) in the schematic above on top of the coil since it was out of the chassis and put it all back together. Still motorboats but I can get a couple stations and if I carefully tune the station there is a point where it will come in clearly without motorboating. Maybe I need to align, have to make a plastic hex nut tool to do that, back to the bench.
