Oh Dear! This item has been sold but take a look around for other similar items

Pulled from very high specification broadcast audio equipment, designed and manufactured by the infamous PKE which later morphed into Elan Audio

PKE (Poul Kirk Electronics, Perth Australia)

Model: unknown

Turns ratio: 1 - 5

Impedance: 200 Ohm - 5K Ohm

Measured DC resistance: 45 Ohm - 600 Ohm

Metal block physical construction (probably mu metal)

Dimensions: 20mm diameter x 20mm height x 20mm width

PCB mounting

4x4 pins plus two tabs for the outer case connections

Each side of the case is marked, I believe these markings indicate as follows:

PEEP - Primary - Earth - Earth - Primary

SEEC - Secondary - Earth - Earth - Common

DC tests confirm this and those Earth points are all connected together but NOT to the case

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

Because I had some basic test equipment on the bench testing other transformers, I went back and confirmed some characteristics of this transformer

 

AWA G232 Audio Oscillator + Leader AC Millivoltmeter

 

100mV input @ 1Khz

Turns ratio is 1 : 5.24

Impedance ratio is 1 : 27.4

Designed and intended for low level analog audio, such as source to equipment input impedance matching.

Stored and provided in a sealed plastic bag.

It would be nice to have more detailed specificatons but I cannot find the datasheets, it would be safe to assume these will be fine up to at least 18Khz (3dB points) - PKE designed and made great, high quality components and equipment for the Australian broadcasting industry.

Testing performed as outlined in the description. Used item, non returnable
