  there is no 1 meg resistor inside the tube socket, must be under the chassis some where. I too noticed the 6U5 / 6G5 thing and changed to a 6U5, no change. how do you read the resistors scott used, body end dot or like modern resistors. they are not dog bones., thanks jimmie

You say 6E5. My AM Philly uses a 6U5 for tuning indicator. I see the FM Philly uses 6E5's.
What about the 1 meg resistor inside the tube socket?

IF alignment.  First check to see that the rotating plates of the air variable capacitors affecting variable selectivity (in square cans under the chassis) are firmly secured to the control shaft.  The pot metal collars used to fix the rotating plates to the shaft have a habit of expanding and allowing the rotating plates to loose electrical connection and proper alignment with the shaft.
