Garey, Thanks for staying with me. OK, to answer all of your questions..... I do have the INJ, and EXC cables connected. My hook up diagram doesn't call for an AGC cable???? On an earlier email you asked Does it do it on power up, no, not until the tubes warm up. The 100 ma is on the plate current meters on each Converter. I did see a real problem...... The internal relay in the TC-6 picks as soon as the high voltage comes on. Looking at the print, I can't see how that is possible. Is it possible that two of the wires in the power multi cable could be shorted? I'll have to fess up, I did rebuild the AC-4 with the Heathkit shop kit, but Other than checking for the correct voltages, I did not open the plug at the end of the multi cable.

I keep thinking of things.... :-) Do you have the INJ and EXC cables connected? AGC?? I doubt it's an oscillation, since both react in the same way. Not likely a bad Driver tube either.. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-A, 4-B, C-Line and TR-4/C Service Supplement CDs <www.k4oah.com> [email protected] wrote: > Back again, > As Soon as I got my TR-3 working, my TC-6, and TC-2 started acting > up.
