Used this to replace a push-pull xfmr with a bad primary on a 1929 Philco 86. Worked great! The compact size allowed me to place it under the original housing to maintain the vintage look and the radio sounds great!

A very good transformer, especially for the price. Audio interstage transformers are hard to get now, and this is a good source. I've used several in past years and had no problems.

Transformers arrived here in Christchurch New Zealand approx 2 weeks from order.Given Covid 19 conditions I am very pleased with this prompt service.Transformers are to be used in the restoration of two 1920's radios, Fada and Stewart Warner and it looks like they are going to be small enough to fit inside the original transformer housings. Good job Antique Electronic Supply.

I used a couple of these on an Atwater Kent model 20 big box, and worked fine.

Perfect drop in replacement for audio interstage transformer for Gibson white panel amps that use a transformer for phase inverter.

Used it to replace a driver transformer for p-p 45s in a GM-253 lowboy ca. 1931-32. Original transformer primary went open after about a month when restored set started being used 2-3 hours a day. My heart sank when I found the open transformer, then found this and was ecstatic. May buy a couple just to have on hand. The set is working great, and its 88 years old!

I was restoring a Freed-Eismann model 15 TRF receiver with two bad audio transformers. This AES transformer is small enough that I could mount two under the chassis and out of site. The sound quality is very good and with enough power to play very loudly on a 1920s Atwater Kent cone speaker (model E as I recall). I also was able to hide this transformer in the can of an AK 20 audio transformer with an open winding (melted out the tar in a stove top oven, gradually raising the temperature until the tar was soft enough to pull out the entire mess with one gentle pull.
