If it has a focus tube pull it out and replace with a 6KV diode (or 3 2KV in series). If you can find a SS HV rect that will help too. Removing filament winding load from a flyback usually cools them well....

Check your HV too if it is low pull the shunt rect cap and see if it gets normal or high if it does that then the regulator circuit has a problem and is overloading the HV winding... which will cause over heat.

My 29JC20 tends to run hot after mitigation of it's issues so I leave the top door open for ventilation cooling.
