I need a replacement for the audio to go with my '70's vintage Cambridge vario. I have an audio, but as yet can't get it to work.

If anyone has a (preferably working) Cambridge audio unit (AU-20, AU-22, or maybe even AU-10) that is gathering dust and that they'd be willing to part with, please drop me a line.

I have an AU-22. No idea where I got it from or if it works. It has an Cambridge Aero Instruments "claim check" tag on it with a Sugarbush airport address. It's yours for some postage. Drop me a line and I will send you some pictures.
