I'm putting together a plan for a Roger Mayer compressor, and I want to put transformers on the inputs and outputs like was done to the one at the old Record Plant.
That one went up for sale recently, and I was able to grab this pic--it shows that the output transformers were UTC A-21s.
However, the input transformers (also UTC A series) are rotated such that you can't see the part number.
I'm trying to deduce what would be the best here-- more A-21s? Or perhaps a 500:50k like an A10 (or clone)?
I'll attach some photos of the Record Plant unit and relevant RM58 documentation
