Hi Surtees, I’m in Auckland and am a quadraphonic novice. I’m looking for a receiver if you know any locals with something decent for sale? Many thx for any help you can give. John V
The 7117 chip is a very crude matrix decoder:

We discussed it a little while ago here-
Simple RM decoder
By far the best thing to do with it!This is good to know, that it's basic crap - because I'm thinking about utilizing the case and maybe some switches to install my SM evaluation boards.
thanks Soundfield!
Is it me or does the Passport "decoder" not look like a repurposed DBX 117 or 119? I'd keep it as is for history sake. It seems to be somewhat rare.
