APPLICATION A generously designed Push-Pull output transformer for use with EL84, 6CA7 valves in Triode or Ultra Linear mode with or without overall negative feedback.
FEATURES 3 inch Grain Oriented (M6) laminated core for minimal losses and distortion. 14 section interleaved primary and secondary windings to give an unusually wide bandwidth. 6 dB per octave roll off at 100 kHz ensures faithful transient response and absence of ringing. Complete absence of resonance effects up to 120 kHz to ensure unconditional stability of the negative feedback can easily be achieved. Two chamber bobbin ensures full capacity and resistance balance to eliminate distortion caused by transformer unbalance.
