I bought the Philco as is at an antique radio show, disassembled it and refinished the cabinet. Then I replaced all the capacitors (from AES)and diagnosed an open primary circuit on the output transformer, a common problem on this model. I found a recommendation on the internet for this AES transformer and the electrical specs were close to the original, as far as I could tell from the limited info on the schematic. One blog reported hum and other issues from an impedance mismatch so I was a little skeptical. But it bolted right up to the same holes in the chassis and I wired to C, 1, and 2 on the secondary side and it works PERFECTLY!!! No hum or buz and the radio works every bit as good as I expected (for a 1941 model). I'm no electronics expert, self taught, so needless to say I was ecstatic to hear it play for the first time, maybe in decades. I'm so glad AES has resto products for a guy like me that likes to bring the dead back to life, so to speak. Thanks AES!

I used this product in a 6V6 push pull circuit and it worked great. Has great sound. The multiple taps are a good feature.

I used the transformer in a Crosley Super 6 Table Radio. The Radio has a push pull audio and the transformer made a perfect replacement. Sounds Great.

A great output transformer. When I replace the old general purpose AES output transformer with this one on my 4 tube DC superheat receiver, the out put volume on the speaker instantly improved. It is a push- pull output transformer but I am using only 2 leads ( red lead omitted) as my audio section is single ended. It is matching great with my 4 ohms speaker. I am using taps C and 1 that gives an output impedance of 9000 ohms.
I will recommend this product strongly.

this transformer was easy to install, and worked very well thanks robin
