Moved to "Philco Electronic Restoration" since we're talking about repairing/restoring a set.
That grid leak resistor will measure 4 meg., or even higher. I can tell you from personal experience that it will need to be replaced. And you want to replace it with a 2 meg resistor for best performance.
The resistor is mounted at the very top of the IF transformer, so it must be removed from its shield can.
What you will need to do, to keep from harming the IF transformer, is to *very carefully* clip the leads of the old resistor right against the body of the old resistor, leaving two pieces of wire still connected to terminals on the IF transformer. Now take your new 2 meg resistor and wrap each lead on each of the short wire stubs you have left from the old resistor. Solder in place with a low wattage soldering iron and replace in the radio.
Do not try to unsolder the old resistor from its terminals, cut the resistor leads off even with the body of the old resistor instead. Don't ask how I know about this...
