Philco model 37-650 issues
#3

Hi Ron, I forgot to mention that it affects all 3 bands but on the AM band it is more noticeable. I did check the primary/secondary windings of the antenna coils and they are ok (I checked them when I had the antenna coil assembly out to change the caps). I do have the donor chassis just in case. I didn't change the 51,000 ohm resistor in the antenna section--it reads about 50k. I do have the link across term. 2 & 3. The B- voltage in the AVC section varies to around -13 V when it is working to around -.6v when the signal gets weak. Thanks, Ken
