Philco 84 code 121 no sound
#49

Terry, I replaced the 1M resistor again, but I also checked cap block 9 to make sure I had the correct values in it. Then I was checking cap block 20. The values are correct and they are wired per the cap block information I have. 20 is a Philco 7762-B which is now a 7762-OEU. That diagram is what I used to stuff it. After looking again at the schematic, it looks to me that the control grid if the 42 output tube passes through both sections of cap 20 to get to ground. The way this is wired I don't see that is possible. The .015 section is from pins 1 and 2. The .001 section is 1 and 3. Seems to me that the .015 section should be pins 2 and 3. Am I reading this wrong? Below is a photo of this block. I know the resistors are not the exact value for 22 and 23, but the ones I used were within 10% of value called for. Everything is de-soldered at this point.

Also last night when I was working on this I did touch the grid cap of the 2nd detector and I do get a "buzz" sound, but not very loud. Touching the grid cap of the det-osc the radio goes silent.
