Remove that .22 from pin 6 and connect it from B- (- side of the filter) and the other end  to the chassis as per the schematic. Leave the .01 and the 470k resistor.

If I'm remembering correctly, I believe that all the filters are grounded to pin 4 of 14A7 (right next to where the .22 is/was attached now). There's a ton of wires and leads attached to pin 4. I'm impressed the manufacturers were able to do it. I do recall that it wasn't the pin the "troubleshooting" section of the schematic showed it to be.

This radio also had a three section cap with one (20 mfd) lead cut and a separate 20mfd installed. I assume it was a repair/replacement.

So attach .22 to pin 4 14A7 then to another convenient ground pin?
