38-116 Code 121 Powering Up Help
#24

I think i am really getting close to my issue(s) now - I disconnected the negative connections I made to the tabs on filter cans 141 and 142 and connected them all to an empty terminal post (that is not grounded). With all the tubes back in (even the questionable 6L6s) I am now getting -47 vdc when connecting the positive lead of my tester to new connection points for the negatives and the negative lead of the chassis connected to the ground post where the positive of 140a goes. For the positive connection of the filter caps 141 and 142 I now get 305 vdc (should be 385) from positive to the filter cap negative. I get 255 vdc from the positive to chassis ground (should be 315 vdc). I also now get -19 vdc at pin 5 of both the 6L6s and at the junction of resistors 134 and 135. And best part is I now get an audible "click" from the speaker when I turn the magnetic tuning switch in and out. I didnt get that before!!
