Archer Video Sound Processor / Dolby Noise Reduction - $25 (Lynnwood)

Strange old box with a few interesting functions, not specific to video.
Can be used to add Dolby noise reduction to any analog audio recording - VHS tape, Reel-to-Reel, cassette, etc.
Can generate "synthetic" stereo channels from a mono audio recording.
(Mono record -> stereo system) Some tape residue on top but front is in great shape.
Powers on, no way to test otherwise.
Too much hifi stuff sitting around! Price fixed but would consider other guitar pedals or guitar gear in trade/partial trade.
Whatcha got? I could use a strat hard case.
