1974 or 75? Looks like the same era as my SX1010. I was a service tech back then, working on the early quadraphonic units. I think the reason it didn't catch fire was the cost of buying two more speakers, which back then was a significant portion of the cost of your system, upwards of half. If there were today's satellite systems with a sub-woofer. The cost would have been much more reasonable and the recording companies would have produced more offerings in 4-channel. Of course it didn't help that there were several competing encoding schemes which only served to confuse customers. This was the "discrete" scheme?
