What's a gimmick winding for?

Post by Ragwire on Tue Jun 04, 2013 7:24 am

I see some IF and RF transformers show a capacitive gimmick winding. I can't for the life of me remember what the purpose is?

Thanks!

A gimmick capacitor is simply wires twisted together. Ofen it is to couple a stage such as a BFO, that will inject a signal into one part of te circuit.
In some vintage Philco sets, it is to feed a little of the output back into a previous stage for reamplification.
The twisted wires act as a very low value capacitor.

Its cheaper than installing a regular capacitor.
