Westinghouse K840CK15 Restoration

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.
