Sowter 9745 response FREQUENCY RESPONSE with 5K source and 600 Ohm load

APPLICATION For use in a high performance valve compressor/amplifier etc where high output level and exceptional bandwidth are required. Designed for use with Push-Pull output stage or an ac coupled cathode follower or SRPP circuit driving a nominal 600 ohm line. Can be configured for low output impedance (10:1) or high level output (5:1) by connecting the twin secondary windings in parallel or series.

FEATURES High grade Grain Oriented Silicon Iron (M6) core. Double two chamber bobbin for geometric balance. Very good bandwidth when driven from a source of up to 10000 Ohms. Normally supplied with colour coded leads. PCB pins or soldertags avaialble as a no charge option for the open style package.
