Fake stereo encoder

[VK5PJ]

Hi,
 some time ago while doing lots of SSB operation on 50 MHz with lots of TV Buzz and QRM, I used a 'fake stereo' encoder to process the audio from my rig to drive my headphones, this gave me a spatial effect on the audio and gave me the ability to concentrate on the wanted signal to the exclusion of most others by their spatial (Right / Left / centre) location as created by the fake stereo encoder.

I have long since lost this little gem and am wondering if any one else has seen a similar device whether a kit (mine was an ETI kit I think) or an already made box?

Regards,

Only things I can find that might fit the bill are:-

Stereo Sound Enhancer ETI 1423 Jun 94

Stereo Simulator EA Apr 83
