SOWTER TYPE SE12

1750 ohms 30W SINGLE ENDED OUTPUT TRANSFORMER FOR PARALELL 300B ETC
FULLY SHROUDED SE12-S
OPEN FRAME SE12-O
ENCAPSULATED SE12-P+
APPLICATION High performance 25W single ended output transformer for use with parallel 300B or similar valves requiring a 1500 ohm reflected load.
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. Optional secondary winding configuration. Optional shrouded, open frame or encapsulated package styles.
