[GreenKeys] UTC Transformer Connection Pin-Outs

[Merz Donald S]

When it comes to researching transformers, I have found that there are 2 =
levels--finding out what the heck kind of transformer the model number =
represents, and then mapping out the connections. For universal audio =
transformers, these connections never seem to be straightforward. Many =
of them have terminals instead of wires, so there is no color code. I =
can figure it out (pretty much) if I have to. But I could also get it =
wrong. Better to have original documentation if at all possible.

So here I am with these big, round UTC transformers. They are definitely =
multi-match audio types of some kind. Two of them are marked CG-3xx, and =
the 3rd one is CVP-3. These are all listed in UTC's 1954 catalog. They =
are all shown as variable match output transformers for PA use (CG =
stands for "Commercial Grade"--whatever that is supposed to signify).

Anyway, does anyone have any UTC documentation that would show the =
wiring diagrams of these output transformers?
Any help appreciated.
Thanks.
