Ex Broadcast Audio - Harbuch Audio Line Transformer 150 Z x 4 AT-203

Pulled from high specification broadcast audio equipment

Harbuch Electronics (Australia)

Model: AT203

Turns ratio: 1 - 1 - 1 - 1

Impedance: 150 - 150 - 150 - 150

That is 4 separate windings, all of which are 150 Ohm impedance

Standard E core style casing

Iron laminations

Dimensions: 45mm wide x 38mm height x 33mm deep

80mm leads

Known to be working prior to dismantling and also DC Ohm tested prior to advertising.

NOTE: Supplied as originally installed i.e two sets of windings are in series, giving an effective impedance of 300 Ohm : 300 Ohm

It would be nice to have more detailed specificatons but I cannot find the datasheets, if this is critical to your use then most likely Harbuch (in Sydney) can provide the specs for you, it would be safe to assume these will be fine up (3dB points) to at least 15Khz

This transformer was used in the output stage of the analog audio equipment, working at line levels
