Still trying to get the corona arc out of this set and to make a long story short I changed the H. Output tube and damper. Then I hooked up my Simpson 260 to the cathode circuit and the set now initially holds about 200mA, but after several minutes builds up to about 250mA which I think is critical if not dangerous to the fly.

I should have just recapped this set, but I wanted to repair it first and see what I have, then consider a full or partial recap. Can someone advise me on what would cause this climb in cathode current and am I going to fry the flyback. It does seem to be running hotter, but not too hot to touch or anything. The darned brand new efficiency coil that seemed to be the only one in the country that I could buy seems to be frozen already! Can't understand that one. It was n.o.s. by Thordarson. I tried turning it from the rear and a chunk of the slug fell out. Geez!

Might have to sell this one to one of the "roundie" pros here!
