I just bought a Zenith Allegro Stereo, model JR596W. It's in overall good shape, except for a few problems, which I'm going to repair. I've been looking at some parts online, but I keep seeing many parts and stereos with the model number HR596W, rather than JR596W, and I can't seem to find what the difference is. I know mine is a JR596W, because it's on a sticker on the bottom. Anyone know? Thanks.

Welcome to the forum! The Allegro line encompassed many models. Seems like a decent enough all-in-one. Beside the JR and HR, there's also a GR, and all three carry the same outward appearance. At least in the few "Allegro" pics I viewed of that style that bother to include a model number!

It could be a different year or a slight change to the turntable. Or different finish. G, H, (did they skip the letter I?), J. I say "J" wins!

Zenith Allegro must be popular. Lots of results to weed through.

It is difficult to find. Keep an eye on ebay.
Be very cautious of websites offering digital downloads, as many of these are scammers.

Sams website will have a copy for $22.00 - be aware that it will not be a high-resolution copy.
