The tail end of that page.

Now, the RCA part numbers for the vertical convergence transformer in the Westinghouse and the transformer in the CT-100 are in fact different; the Westinghouse is 241T1 while the CT-100 uses part 3T127.

But, I have a parts catalog that shows them cross-listed as identical. I think it is safe to assume they're the same part; one part number used for OEM transformers in sets built by other manufacturers, one part number for sets built in-house by RCA.

The different part numbers can be accounted for by the fact that in the CT100 the transformer is "potted" in a 5 sided metal box that bolts onto the back of the HV cage. In the Westy, it is just an open frame transformer similar in appearance to a regular vertical output trans.

I wonder why RCA took the trouble to put the transformer in a “box”? Isolation? Did this part fail in the CT-100 as much as the Westy?

No way to know why RCA potted it in a box. Perhaps to better protect it from high humidity or dampness. Failure seems to be across the board in all the sets this trans is installed in. May have been due to defective materials or poor engineering.

Transformer ordered and shipped. Recapping continues, finding poor resistors along the way.
