Greetings. I have in my possession a transformer which I pulled out of an old basketcase Twin Reverb. It was at some point the reverb driver transformer in that amplifier. I would like to use it for an outboard reverb unit I plan on building. The problem is, it does not look like the reverb transformers I have interacted with before and the DC resistances are not what I would expect for the normal 20kΩ:8Ω units. The transformer has two sets of leads, blue-blue and white-orange. Blue to blue measures ~1.23Ω White to orange measures ~548Ω The only markings on the case of the transformer is 'T11' on the underside, which sounds like a component number rather than a model number to me. There are no other markings. Is it possible to positively identify this unit? I do not have a signal generator, unfortunately. Looking at the specs of hammond transformers, their 20kΩ:8Ω transformers have a DCR of 1240Ω:0.9Ω. They have a similar model which is 10kΩ:8Ω which has a DCR of 575Ω:0.9Ω. That is pretty close, but is it close enough?
