Please help with the Philco 71B, my first time trouble shooting.
#8

Yes I have changed the 36 tube twice, the one that was in the radio set tested good but I do not know about shorts, I don't think there are any, as crazy as it sounds I have to restore my tube tester as well its about 75 years old and I don't really trust the short light on it, but for all I know it could be great. I just finished scrubbing each of the tube contact sockets with de-oxit as the set is dirty, I am going to wait for it to dry and then try it out again (most likely this is not the problem but it never hurts to try), after it was suggested by a fellow hobby member to pull each tube in the string leaving the 42 in place to try and pin point what section the static is in. Hopefully this helps, I will try here soon.

Any other suggestions would be great, Ron if you are browsing hopefully you will stumble across this post, I am also looking for the ohm readouts of each coil if anybody has them, there are not any on the schematic.

Thank you all so far for your help.

Jon
