Thanks for the help. I'll look into that much closer.
The unit in the photos of this post will also get a good looking over. I just don't want to invest much into them, as they come up all the time around these parts, and it's only a matter of time until one that has a totally working turntable come up.
This is kinda fun. A nice break from my antique radio addiction that ends up costing me a lot of money.
