MAJOR score today. I went to the only place left around here that ever repaired TVs. The owner sold me a B&K HV probe for $35. Also, they still have a room full of tubes, so I grabbed a horizontal output tube and a HV rectifier for beans. I haven't had time to try the stuff, but my HO tube showed shorts on my Hickok 6000A. Perhaps that is the cause of these issues. I will know soon. Very happy with the finds!
