Keeping flybacks cool

Andy: Thanks for the tip. I'll try it with my CTC-4, which also runs hot. Thats why they put a "chimney" on the HV cage! LOL.

Please measure the HOT currents first. What is the recommended current? Why is it hot?

With L117 you can adjust the horizontal output current.

Another hint: try it with a variac. 110V to 117V--with which mains voltage the flyback keeps cool?

A van is noisy and it is a deviation from original status.
