Stancor 10A6 Interstage Transformer 20K:80K Federal, UA 175, Kenyon, UTC

Specifications

For sale is one Stancor Interstage transformer (single plate to pp grids). This was not a standard catalog item and was most likely a custom part # for a military, industrial or broadcast product built in the 40s-50s. The solder pins are clean and the unit appears to be unused. All windings test good and the DC resistance results are shown in the photos. The voltage step up gain when the secondary is wired in series is 1:2, and impedance loading tests suggest an impedance ratio of about 15-20K:80K , similar to a UTC A-19. Great for DIY tube builds.
