40-180 tube changes
#1

.pdf 40-180.pdf Size: 529.88 KB  Downloads: 250


Apparently in run 4, the 7J7 was replaced with a 6J8. I can find the pinouts on the 7J7, but I can't find anything on the 6J8. Does anyone have not only the pinouts of the 6J8, but how it should be wired? I'm replacing resistors around that tube, and R29 keeps heating up. Don't know if the radio ever worked or not. Caps have all been replaced. There is also a 150ohm resistor added to the plates of that tube, but I'm not sure where as I don't know the pinouts. Can someone help me out?
