The one thing I noticed, and Tom did as well, is the flyback get's very hot after awhile and starts to drip wax. This is about after an hour on for him, and an hour on for me when I noticed it was hot. It's set correctly and Tom will chime in on that, or you can check the last parts of the CTC16 thread and see.

Do RCA Fly's just run really hot? And if so, would it hurt anything if I cut open the flyback box and installed a small computer fan to it externally, to suck cool air though the box so the Fly isn't sitting in there melting it self to death?

I was also thinking of putting a small computer fan on the top of the HV cage in my 1954 CTC2B, 21CT55 21 inch color. I don't see where it would cause any harm. Yes, I have always thought that around 210 ma was about the max that the cathode current should be at. The HV cage on that old set is completely enclosed except for a hole in the top with a "chimney cap", in which I could install a fan. Possibly the reason that HV cages as so tightly enclosed it to reduce x-radiation.
