Okay, will go back through it looking for bad grounds. I get 0 ohms from ground of volume control to ground of wire round. I am aware of the oddity of this volume circuit, and low volumes affect the detector's cathodes as well, non linear region possibly. I did notice the inner 5k of the dual volume does not track linear with rotation checking with ohm meter, and I don't see much change there until almost half rotation, then everything is fine. Have not disassembled the volume to clean, just cleaner through the holes. After recap I noticed a low level hum, almost like a ground loop hum, not lytic loud hum, I was running 40mfd's and it was not evident, running 10's now and it is, but might point to bad ground somewhere. I ran one first position 10 and last a 40mfd and it was better than two 10mfd lytics. You can feel it in the speaker, so something is not right. This is an early non avc unit serial 850023. I will check my work also looking for errors. Thanks.
