I tried to post this earlier, but I have no idea why it never posted. I bought a Motorola 4 channel receiver with 4 channel inputs and even a place for a Quad FM Decoder, although someone on audiokarma mentioned this technology was never implemented. I do not have 16 ohm speakers in a proper box, but the back clearly states ONLY to use 16 ohm speakers. I did buy some cheap papercone 16 ohm speakers just to test, but I do not have any quad material to test it with, so I am at a bit of a loss. I have since bought a Marantz 4230 for relatively cheap, but it is modestly powered and I have plans to restore it and get it in good shape. The Motorola claims to be a 120 Watt system, which would mean, I think, about 40 WPC when running quad (correct me if this is not so). So I believe my question here is first, does anyone have any information about the Motorola Quadraline receiver (not the 8 track automobile receiver)? I believe Motorola was an OEM manufacturer of sq decoders, and this one has a "77" on the back which I am assuming means it was made after the more popular Quadraphonic technologies had developed, so I have high hopes for it. I have pictures online of the item, including some of the inside of the chassis. I added the html last time, but this may be why the original never posted, so I will leave them off for now. Here is a picture of the unit at least for reference.
