Vintage 1960’s-70’s JBL 5901 mic input transformers, lot of 3. These are 150Ω:60kΩ (1:20 ratio), and would be great as a mic input for a JFET or tube mic pre. Years ago I also wired them in reverse as instrument DI’s, and they sounded great. Been hoarding these and it’s time to pass them on to someone who’ll put them to use.


Measurements are as follows:

T1 Pri: DCR 41Ω, L 10.67mH

T2 Pri: DCR 43.5Ω, L 11.03mH

T3 Pri: DCR 40.9Ω, L 10.81mH

T1 Sec: DCR 2.83kΩ, L 5.19H

T2 Sec: DCR 2.88kΩ, L 5.43H

T3 Sec: DCR 2.87kΩ, L 5.27H

Inductance was measured at 10kHz.
