Bandwidth spec's are not available for this model. Hammond has similar interstage transformers such as the P-T124B with frequency response spec's and graphs available in their datasheets.

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.

I used this transformer to replace an interstage transformer in an Atwater Kent model 20C radio with an open primary winding. After removing the old transformer from it`s can, I striped the outer mounting bracket off the new transformer, and hot melt glued it into the original transformer can. It works great! Thank You!

Excellent solution for audio interstage transformers on a Bosch Model 35. Fits nicely in original housing. Great product.

Great audio interstage transformer for repairing vintage Atwater Kent Radios. The tapped secondary is very handy when a reduced impedance is required for the final stage.
