APPLICATION A high performance output transformer for push-pull KT66 or EL84 etc in Pentode UL or triode mode or similar valves. Replacement for Leak TL12 or TL25 | |||
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. The original Leak TL12 had 2/8/18/32 ohm secondary which is available on request. | |||
