108.253.181.30
Found this at a swap meet for $10.
I want to try it with my Technics RS-1500.
I don't have a manual, (although I did see a service manual on-line.)
Anyone have any advice, PDF's, or anything on it?

One of the many Dolby B units I fooled with.
If you don't have a calibration tape, buy a Barclay-Crocker tape on eBay and use the tones on it.
Not too shabby sounding when it worked. Mostly discrete components but the circuit board is pretty brittle. Mine was cracked.
IMHO, you paid what it's probably worth (I think that's how much I paid)
maybe "We" can identify it as a rebadged version of another Dolby unit (e.g., TEAC's).
If so, maybe one can find a manual for it under another name.
I'd say just hook it up & try it -- but I do think there's some calibration involved in using an add on, outboard Dolby compander.
all the best,

here it is.
it has been suggested that it is was made for Concord by Nakamichi.

Concord was a pretty upscale car and home audio company. I think it was somehow associated with Lear when the personal jet company was making audio gear too.
From the looks of the circuits, I'd place it at the same time as the Advent 100(A) Dolby units.
You might look under the hood. Some of those units had schematics glued to the lids.
There is no schematic either on the top chassis plate, or the removable bottom plate.
BTW, it is completely free of IC's, that suprised me.

not that I know who their OEM was, either.
It doesn't look like the TEAC of that era (which was what I was thinking/hoping for).
all the best,
