Bought this to replace a fried interstage transformer on a Philco Model 20. A 27 tube drives two 71 tubes that are connected using this transformer. Works good with no issues so far. Great price

Great replacement transformer for the 1920s radios- works great. In most cases, the transformer will fit in the original can after the tar and original transformer are removed or also fit inside the old transformer housing. Have used about 20 so far. Nice product.

Used to replace defective transformer in a Atwater Kent model 20. Fits inside of old transformer can and works very well.

Good for replacing audios in old radios

Works great between #27 tubes. Must always review plate current to ensure your within the transformer current limits

I thought "no way this will work in my Crosley 124", but it worked perfectly and the radio plays great. And the price was reasonable, especially for a part I thought I'd never find

Worked good in my 90 y/o All American Mohawk. The bass response may be a little soft, but it's loud and clear, feeding a Class AB2 output circuit.

The transformer was used in a Columbia 5 tube TRF receiver, also known as a Radynola 5 tube radio circa ~1926.
The original had an open secondary. This replacement transformer seems to work just fine.

I used this to replace the push-pull audio input transformer on my Philco Model 20 radio from 1931. The old transformer had an open primary winding. This replacement works extremely well.

Very pleased!! I jave installed MANY of these transformers in many makes and models with great success! Very pleased!!
