SOWTER AUDIO TRANSFORMERS
8665 HEADPHONE OUTPUT TRANSFORMER

8665 50% MUMETAL HEADPHONE OIUTPUT TRANSFORMER

APPLICATION Designed to be driven from a cathode follower output stage or SRPP circuit via a coupling capacitor. Suitable for headphones with an impedance in the range 30 to 600 ohms.
FEATURES Combination core using High grade Grain Oriented Silicon Iron (M6) and Mumetal (76% Nickel). This provides a high level capability and ultra low distortion, exceptional bandwidth and transient response which is maintained over the full dynamic range. Three separate secondary windings are provided which may be connected in series or parallel for 30 to 100, 100 to 250, 250 to 600 ohms headphones. Various package options. Leads, PCB Pins or Solder Tags.
