Excellent choice for early antique radio audio transformer coil replacement. Fits many old audio iron with a 1/2 inch iron core, Crosley, RCA, Adams Morgan to name a few. Good quality for a good price!

Great way to rehab old burned out xformers.

This is a very handy alternative when looking for a 3:1 transformer replacement core. I've used many of these and they work fantastic. I only wish they had a 5:1 version available.

This transformer coil I used in repair of a Radiola 3. The original transformer had open windings. I took the original transformer apart, removed the bad core, and reused the laminations with this new core. The radio works like new and looks original.

The price was right, ordering easy, and fast delivery.

very good

Very pleased!! Worked very well!!

Did the job! I used this as a replacement audio transformer in my old Westinghouse RC. With a little bit of finesse it fit over the old core and now my 100 year old radio is back in action. Too bad there's nothing to listen to on AM...

They fit inside the shells of the original transformers on my crosley trirdyn 3r3 and seem to work fine.

Good fit. Used on many repairs without failures

This is my second order for these audio transformer coil assemblies. I have had a chance to test the (2) coils from my first order. I used them to repair mouse damaged F-E (Amertran) audio transformers in a Freed-Eisemann NR-7. They work well as replacements for bad coils. I bought this latest coil to repair a bad "audio" in an NR-6 Model.
