Here are a few different variations of the Technics CD-4 package. Apparently these seem to be much more common and were sold outside of Japan but not in the US. The Technics SS-2900D is shown in the first picture. Same general package but the receiver seems to be a bit thriftier with no scope and a different tuning dial. I think that they both look nice but the SS-2900 looks a bit cheaper than the one below. Well at least to me it does.
And here is a great picture of one that seems to be identical to mine but minus the scope with a Technics reel to reel and a pair of mismatched speakers. It is model number SC-2200DX.
And here is a fourth model, the SC-8400dx which seems to be the bottom of the line model. No adjustable AFD but two matrix positions. Confusing yes?
And even another one. The SS-7700 which looks to be a bit more modern......well at least by a couple of years. Not sure if this was sold in the US or not? I kinda like the looks of it and especially the turntable with the silver and black base. Didn’t seem to come with a cabinet from what I can tell.
