Hi- just signed on to take a look at this catalog, but I don't see it in the thread. Is there someplace I'm not looking?

Just got myself a free '63 Astro-Sonic tube model today. Trying to figure out the style, etc. It's a model 16T626R, serial #1677915. I have heard that they switched from tubes to solid state in '63, so I was surprised to see the tubes. Maybe it's actually a '62? 1963 was handwritten in the manual by the original owner, so maybe that's just when it was purchased.

Haven't done anything with it yet. Former owner tells me it works great in all aspects. It belonged to her parents, the original owners. I'm no radio person, so any tips would be helpful. I'm about to unscrew the back for a good cleaning on the interior before I move it to it's spot to plug it in.
Also- where to buy user-replacement parts such as stylus? Probably could stand to have a new one I'm guessing, but the jury is still out on everything at this point.
