I pulled it out to take the measurements in the pics. The flyback is sparking all over so no point in plugging anything back in yet.

Electrohome G07 may be compatible with that tube.

grantspain:

is there not a code on the flyback

Ken Layton:

There must be a label on the flyback with part numbers.

Could be a possibility the B+ voltage is too high and the safety shutdown circuit isn't working.

Is there cracks in the flyback?

This POS chassis doesn't even have a shutdown circuit. The shutdown pin (9) of the HA11235 is not used!
