Not quite sure what it is, but looks legit

Is this for testing home equipment? Or quad jukeboxes? Or what? Anyone ever seen one of these?

Demo tool for aftermarket car stereo, i presume...

I don't know but I have seen it for sale previously.

This thing looks like some sort of demonstration tool to show off quad in the early 70's, I'm guessing that you could play with the speaker balance or isolate one or more channels at a time, but i think we would really need someone like quad linda to chime in here.

Yes, it seems to appear every now and again, wonder why it doesn't sell - only $170+shipping!! If I'd made that in my shed I'd feel embarrassed. If anyone would like a pile of old wire and some forty year old switches I can probably help you out for slightly less than the asking price!!!

I have both Motorola Quadralines and while this would be a hoot to have at car shows, I don't see it's value at $150.
$25 I'd be all over it, though.

I love this part...

Seller Notes: “Used, untested, should work fine.”

Uh, what if it doesn’t? I just purchased a brick with wires.

Over the past few months I've been looking through vintage Billboard magazines online, searching for interesting quad tidbits, and I came across this:

I think the mystery behind this quadraphonic "table tennis paddle" has been solved.
