I recently performed a re-cap of this 47-1230. The radio has been working fine since. Then a couple months later, a puff of smoke and it died. A visual inspection revealed that the R315 1K resistor had fried. I have the paperwork from Chuck but I'm having trouble sizing it for posting here so I've added the link from NA to the schematic. Problem is in "Section 3" of the schematic.

The problem appears to be on the Z302 IF side of the resistor. I isolated the red wire from Z302 and my resistor doesn't fry. I checked the resistances of Z302 and I may have an anomaly. Reading from the red wire to the blue wire I have 11 ohms. This matches the schematic. Orange wire to yellow wire is about 4 ohms.? But from the green wire to pin 4 of the 7R7 tube I see about 7.2 meg. This is way over the 10 ohms on the schematic. I hope I'm measuring the correct points. This 7.2 meg is seen across the green wire and the white wire which connects to pin 4 of the 7R7. White wire not labeled "White" on the schematic.

I believe my problem is inside the Z302 IF but I wanted another opinion before I open up that can. Am I going in the right direction with my troubleshooting?
