SOWTER Type SA08

High performance Single Ended Output Transformer for 300B Triode

PACKAGE OPTIONS STYLE CODE
Fully Shrouded S
Encapsulated P+
APPLICATION A conservatively rated transformer optimized for the 300B triode.
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. 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.
