This came in with the HOT shorted. Replaced HOT with OEM and Damper diode replaced caps in power supply. Standby voltage is correct. When power button pushed high voltage starts to come up but stops at 5K, Regulated B+ is ok. Now here's what I tried. I took the horizontal yoke plug off and high voltage came right up, then shut off then right up again, then poof went the HOT.My question is by pulling the yoke did I Change the timing for the HOT enough for it to run without shutting down or do I have a bad yoke? Yoke rings 17 rings GOOD. Fly rings 27 rings GOOD. I don't have another HOT so I have to find the answer. al marquardt ampm@xxxxxxx Al Marquardt Electronic Repair 206 W Main Girardville Pa. 17935 ***************************************************************************** Classifieds!
