Description

ONE PAIR of 455 kHz IF Transformers (one INPUT marked CI-29 and one OUTPUT marked CI-30).
Size is 1-3/4 inch square by 4-1/16 inches tall.  These are USED in EXCELLENT CONDITION with original color-coded push-back wire leads.  The green (grid) lead of the input transformer has a grid cap attached but can be rerouted to emerge from the bottom of the shield like the other leads.  Both transformers have been tested for resonance at 455 kHz with a URM-25 Signal Generator and an HP Scope. You will need to adjust their Top-Tuned trimmer capacitors for resonance at 455 kHz in your circuit. They mount with 6-32 threaded spade bolts and nuts (included).  Use these for repair of  radios from the 1930s thru 1940s or for new homebrew construction.
All items carefully packed.  No returns unless not as described.  If there is any discrepancy, contact me first and I will try to make it right.
