I just can't take it anymore. They are not. The standard quote used to hawk these:
There's a steady stream of severely overpriced ebay listings for these things. PT Barnum at his best.
Gee, they are similar in size and style. The relationship ends there. These things are found on the lower quality industrial and PA line products, and have a full octave less bottom end than any of the 'good' RCA transformers. In short, these are the last RCA transformers I'd ever use for any sort of build, and they tend to get offered at 1.5-2x the typical price of the actual good RCA stuff. I'm going to use good vintage when I can, but I'm going to buy Cinemag or Jensen before I use these. $100/ea is really too much for these, $50/ea is more reasonable.
You have been warned....carry on.
From what I have researched these they are the RCA version of the Western Electric [Edited model # out because Google is making it look like they are related]
