APPLICATION

Exceptionally high performance 600 ohm line output transformer. Developed for use in the Pulteq EQP-1A Equalizer.  Can also be used 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. 9530e tested with Drip Electronics PCB

FEATURES

Combination Mumetal and Grain Oriented (M6) laminated core for minimal distortion and a good output level. The Mumetal core ensures the low distortion, frequency and transient response is maintained even at very low levels where the ear less sensitive. Geometrically balanced, multiple interleaved primary and secondary windings to give an unusually wide bandwidth. The centre tapped winding for negative feedback is bifilar wound with the primary which ensures minimal phase shift and high stability of the feedback loop.
