Looking for a flyback for a RCA CTC 15

How did you get the tire off? Does the core come apart in the middle? I don’t see how you can get the tire off the core

The RCA ones come apart quite easily. Straighten the one tab at the top of the frame above the stamped numbers and pull. Sometimes there are spacers between the 2 core pieces, have to be careful to put them back.

Question on using a new silicon diode for the focus rectifier vs original tube diodes. I like the idea of removing the heater current from the flyback, is there any concern around an increased focus voltage or the change in reverse resistance?

To further "lighten" the load on the flyback is there any reason not to use a silicon diode for the HV rectifier too? Note I understand there is a line to where you should just get a modern TV, but flyback transformers are getting hard to find.

I have also seen they use to make solid state devices that plug into the tube socket but I had thought I read they are prone too fail and it is just better to keep using a tube, not sure if that is because they were selenium, wrong ratings, or just 50+ years old.
