| APPLICATION Exceptionally
high bandwidth 600 ohm line output transformers. 2 different ratios for
Push-Pull, ac coupled Cathode Follower and SSRP circuits etc. Ideal for
HiFi pre-amplifiers, Microphone amplifiers, Compressors, Equalizers etc.
Ideal for 6SN7 or ECC83 valves. Suitable as replacement for original
transformer in many vintage recording studio units. The fully balanced output winding ensures isolation from ground noise, noise pick-up in cables and elimination of clicks and bangs when the connections to other equipment are switched. Reduces the output source impedance of the circuit to ensure performance is independent of cable length and multiple loads. |

| FEATURES Combination Mumetal and Grain Oriented (M6) laminated core for minimal distortion and a good output level. The Mumetal core ensures the LF response is maintained even at very low levels where the ear less sensitive. Multiple interleaved primary and secondary windings to give an unusually wide bandwidth. Additional centre tapped winding for negative feedback. | ||
