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? Barry 4 answers

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

I have a Atwater Kent 10B and in the 3 tube detector can there are 2 transformers, both open, that I need to replace. If I remove old and potting material will this work for me? If not a recommendation please! Tom SFSD

The AC reactance (XL) is typically 5-6 times the DC resistance (R). Therefore the total AC impedance will be Z= [R^2+XL^2]^0.5 so it should work fine.

We do not offer technical support or service here at AES and as such we could offer advice in terms of working on your unit.

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. Bruce1 answers

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.
