Sorry for the erroneous post.
In all my catalogs, CG refers to audio transformers. Are you sure of the
number?
CG means "commercial grade". It applies to both audio and power
transformers. This line of transformers was originally designated "PA"
(public address). The CG numbers and PA numbers are the same, and the
electrical characterists are usually t he same, but they may be physcially
different. The changeover took place in 1948.
CG (and PA) is UTC's mid-line. It includes the CVM and VM series modulation
transformers. Their top line was the LS series. There are audio and power
LS transformers as well. LS transformers were very expensive, even before
WWII. LS audio transformers are rated as hi-fi and suitable for broadcast
service.
Their lowest grade transformers are the S series. These are typical "ham
radio" qualty transformers, with marginal power/voltage ratings and mediocre
audio performance.
I'll look up the transformer when I get home f rom work.
