Sowter type 1160 Style S Size DS
APPLICATION High performance line output transformer for driving from a single ended stage. Suitable for tubes such as 12BH7 up to 20 mA quiescent current side. Two identical secondary windings which may be connected in series or paralel for 600/150 Ohms. replacement for Chicago BO-1 in Fairchild 666
FEATURES High primary inductance for high bandwidth even when driven from high impedance valves. Multiple interleaved windings for exceptional HF response. Typically 70 kHz bandwidth. 100% M6 core for high level with minimal distortion. Can be configured for 5:1 ratio ot 10:1 ratio to adjust output impedance/level. Low dc resistance to ensure very low output impedance in application. Load seen by anodes can be adjusted by using a secondary load resistor. Package options. Colour coded leads, PCB pins or Tags. Shrouded Open frame or drop through package options.
