38-116 Code 121 Powering Up Help
#20

did some more measuring this am. I have 0 vdc at the juncture of resistors 134 and 135. I also have 0 vdc at the ground point where the 10 mfd e cap (140a) positive is connected. I also checked the 6 vertical pins on the bottom of the audio interstage transformer - the three on the left should be -21 vdc and they are all 0. the top on on the right should be 21 vdc and it is also 0. the bottom two on the right should be ~260 vdc and I get 260 vdc. I have not disconnected 140 yet but will do that next.
