This is really interesting. I have a 25MC33 Zenith Roundie and I have had this happen twice with the vertical output transformer. I would definitely like to find a permanent fix. If better replacements could be made, I would be interested in buying one. This does seem to be the only real weakness in the Zenith roundie design. Lets us know what happens with the transformer.

On mine, the center winding was plate with the inner most being B+ the the outside of that winding being plate, tape, convergence windings the on the outside the yoke drive winding.
I would be curious to know about what it cost to get one rewound? I wonder they could do flybacks...

I would be interested in getting an upgraded new unit if the cost was not too high. I feel on Zeniths the vert output TX is a weak spot. I've had several fail just like listed here. Even had one go bad on a 71 25" Zenith "B" line chassis.
