Well, I brought the RS35A (over 30 years old I think) and cable from the home QTH to start substituting. First though, I cleaned the cable ends of the offending set up and it tested at 13.8v. I plugged it into the K3 and it fired up. Then I transmitted at low power and started getting feedback in the audio channel and power output on the K3 showed that it was varying when in tune. I turned off the supply and had a bite to eat. When I returned to the shack planning on testing the voltage under power using the VFO B display on the rig, it refused to turn on as did the keyer. I checked the voltage at the PS terminals and it registered 0.8v DC. I took the fuse out, cleaned it good, checked continuity, used Deoxit and still 0.8v DC. Also confirmed that the outlet was 117v AC. Will use my old power supply tomorrow. This power supply is two years old. Guess I'll take it home and start reading up on troubleshooting but would love to hear ideas about what probably went wrong and what to test for.
