Removed from 1950s-vintage british-made studio equipment.
Guaranteed to have flat frequency response across the whole audible frequency range.
Made by EMI.
Why these have a reputation for being the best:
As a credential of top vintage mojo..
EMI also built Abbey Road Studios, (the whole studios) including the original mixing desks, which were used to record Sgt. Peppers by The Beatles, and many other 1960s classics.
The 92925D was probably employed at Abbey Rd. In any case it is built to the same top-quality-level as the audio transformers that EMI made for Abbey Road.
Inputs can be connected in balanced or unbalanced configuration.
Outputs are unbalanced.
Can be wired directly in between a record player (using an MC cartridge) output, and the MM input on a hi-fi amplifier, to provide the gain and matching required.
Measured for DC resistance (DC resistance shown on label in photo).
equating to approx. 30 Ohms input impedance/ 50 kOhms output impedance.
Weight: 4oz (approx 112g), including wires.
I have a long standing reputation as a 100% reliable and helpful ebay seller.
