For Sale: Very nice Grado Stero Transformer Model F10-35. Most likely made in the late 1950's. Mint or near mint shape.
Don't have any moving coil carts to test this with but with my meter got approx. 1100 ohms on each of the RCA output cables and almost exactly 100 ohms each on both 1 and 2 inputs. This came from an estate sale in a home console with all tube componentes- a Madison Fielding preamp, a Scott S-3000 II tuner, a Scot 710 Stobosonic turntable - and they all were in pretty good working condition.
On the label:
NOTE: With a source impedance of 600 ohms per channel and secondary termination of 47,000 ohms per channel frequency respons will be 10-30,000 cps +- 1 DB. Channel seperation 50 DB. Channel output balance +- .2 DB.
