Flyback fire

[wkand]

Would an outfit like Moyer still have a Crosley fly? Wow, they musta bought a lot of NOS?

The wax coating is peeling off of the flyback on my Zenith bugeye. The fly doesn't get very hot, so I'm thinking that this may have occurred when the set was being played in the antique mall, for hours on end, without being recapped. Should I coat the fly in silicone or some other insulator?

I use silicone rubber that you can find at radio shack. Discharge the crt just to be safe and clean the dust and dirt off the flyback before you apply it. Silicone rubber has a nasty smell when you first put it on but after it cures it will go away.

Good tip! I've used rubber cement on one or two in the dim dark past, and have also used "corona dope" but the hazard with either is that it needs several days of curing time before the set can be operated. Otherwise the flyback will burst into flames.

If the smell of the silicon rubber is offensive one might try the sealant made for repairing leaky fish tanks. Such can be had at a pet supply store in the aquarium department. It is far less malodorous.
