I recapped this Philco awhile back. Sounded fine, but now it has developed an AC hum and lost all reception. I have by-passed and checked both filters and they are fine. If I put my probes on the 42's K and P, no scratching in the speaker. Any suggestions? Also, my Riders says with Run# 7 resistor #19, part # 4518 (5,000 ohm) should be changed to a 99,000 ohm. My schematic shows that resistor #19 is a 51,000 ohm. Any help there as well.
Thanks in advance.
