You have the impedance of 10k and 90k, but the schematic for my radio is dc ohms (2k and 13k). Can you tell me the dc resistance of the primary and CT secondary for this transformer?
Asked by Anonymous on December 16th, 2016.
The measurements that I took in DC were as follows: Green to Green 1.5K Green to Black( which I can only assume is the CT) .70k and the Red to Blue is .4k

Will this work on my 1922 Crosley battery set ?
Asked by Anonymous on December 16th, 2016.
We wouldn't be able to guarantee compatibility with your particular set as we do not have the reference materials needed to do so. However, this transformer is equivalent to the Stancor A53-C so I would recommend researching the compatibility of that model with your set.

I have a CGE. Model 93 and told it is like a Radiola 111A & Westinghouse 53 I need audio transformers for. I was told these would work is this true. If so I will need to get some.

Unfortunately we couldn't speak to the compatibility of this transformer with your unit. I would suggest seeking out a reputable tech in your area who may be able to determine compatibility based on the needs of the radio and the specs of the transformer.

I have Chelsea Super 5 1925 battery radio where both interstage transformers are open, will this product suffice to get the radio operational?

We are not techs and are not sure if this will work in your situation.

I own a Fender Musicmaster Bass amp, which is the only amp made by Fender that used an interstage tranformer as the phase inverter. I bought this transformer to build a clone of the Musicmaster Amp. Does it work? YES, this interstage transformer can be used to build a Musicmaster amp clone. There is not a lot of tech info on the forums about interstage transformers being used as phase inverters. My measurements on my clone build compared to my "real" Fender, confirm that this is a suitable replacement for Fender part 026847a used in my 1978 Musicmaster Bass Amp. The transformer sold here is physically smaller than the Fender part.
