[AMRadio] UTC S-21 specification

[Bill Smith]

"UTC Special Series transformers are specifically designed for amateur and
popular-priced PA service.  These units are finished in a rich, commercial
type medum gray enamel.  A recessed terminal strip is provided, permitting
above chassis or breadboard wiring in addition to standard chassis type."

S-21 Universal Modulation, Any Class B primary, Any Class C secondary, 110
watts G7 Case, sold for $21 in 1963.  (From Elmar/Masters Catalog)

Must say, the input and output impedance rating appears rather strange.  No
turns radios or impedance specified, nor current ratings.

G7 Case: 4-5/8 x 4-5/8 x 5-1/2" 8 lbs.

Perhaps someone else has better detail.
