Okay, I just looked at Bulletin 280...boy, did someone at Philco screw up on that one...everywhere you see resistors in the parts list with "mmf" or "mf," substitute the word ohms.

Are you saying a white body with orange paint on one end, or orange on one side, close to - but not on - an end of the resistor? The schematic does not show any resistor on the screen grid of the 6F6G. What does the other end of this resistor connect to?

As for the other resistor (yellow body with white ring?), it could be yellow body - white end - yellow dot (not seen because of the yellow body), which would be 490,000 ohms (490K). There is a 490K resistor in the vicinity of the 6J5G, resistor (21), which is 1/2 watt. One end connects to the junction of resistor (20) and capacitors (19D) and (24); the other end connects to ground.
