APPLICATION A low priced high performance output transformer for push-pull 300B or similar valves. | |||
FEATURES Highest grade low loss (M6) grain oriented silicon iron core for minimal distortion. 14 interleaved winding sections to maximize bandwidth and ensure clean transient response. Two chamber bobbin to ensure full geometric balance. Low copper resistance to minimize losses and maximize loudspeaker damping. 4 separate secondary windings (See below) for optimum matching to load without the use of tapped windings which can reduce HF response. Other secondary configurations available at time of order. Various package options. | |||
