lol if I would have thought about that fan in the HV cage for just a moment I would have realized how bad idea that would be

as well as I have been thinking of going ss on that to lower the heater load to help the flyback..
well it can't hurt to get some practice setting up them grey scale settings. I will also try pulling the vertical tube as well and try it that way as well and get a feel for things.
The RCA book mentions flipping the kine bias switch and video peaking switch. I am curious the operation behind these switches and what they do?
