I spotted these on EBay UK for what looks like a very good price. There are still plenty left. The transformers have 150+150:600:37.5 windings and are specified as +/-0.1dB 40-15000Hz at +20dB when terminated correctly. Apparently each one weighs approx 500g.

Given the price I thought I'd grab a few. Looks like it could be a nice 600:600 output transformer for a preamp or Vout DAC, and possibly a good matching transformer to couple low impedance headphones to a high output impedance amplifier (using the 37.5ohm winding for output).
I also wondered if the 37.5ohm winding could be used in some sort of feedback role to linearise the transformer....?
Any experience, thoughts, recommendations would be much appreciated.
