Sowter Type 9050

Double Triode to 600 ohm Line Output Transformer

Coloured Leads 9050-A
Solder Tags 9050-X
PCB Pins 9050-B

APPLICATION For use in a high performance valve compressor/amplifier etc. Designed for use with a double triode such as an ECC83 or 6SN7 in push-pull driving a nominal 600 ohm line. We recommend using a secondary load resistor. 600 ohms will provide a constant reflected anode to anode load of 16000 ohms when the amplifier is feeding a typical 600 ohm line. This also lowers the effective output impedance of the amplifier.
FEATURES Combination core using High grade Grain Oriented Silicon Iron (M6) and Mumetal (76% Nickel). This provides a high level capability, exceptional bandwidth and transient response which is maintained over the full dynamic range. This core also permits the use of a relatively high ratio which ensures a low output impedance for driving lines or complex loads.
RATIO 6 : 1
MAXIMUM OUTPUT LEVEL 0.5 % THD at 50 Hz +30 dBu
Max dc current per anode 30 mA
Max unbalance current 500 uA
FREQUENCY RESPONSE 8K0 source 600 ohm load +/- 0.5 dB 10Hz to 50KHz
TOTAL DC RESISTANCE referred to secondary 34 ohms
EFFECTIVE OUTPUT IMPEDANCE (with 600 ohm secondary resistor) 175 ohms
