It's an 8-tube to be sure. I'll go with Mike on this one; B835R (the letter on the end I'm sure describes finish color). I have that radio in my stack and it's very similar to the Y832; same face layout, slightly different cabinet. The Y832 also has the 'High Fidelity' script next to the volume, but both radios have the power indicator lamp above the same knob. Zenith stopped doing that on table radios until the MJ 1035.
Don't mess around; re-cap it and put a fuse in the line cord. Also, don't rub too hard on the dial-plate; that gold finish is very thin and rubs off easily.
Enjoy!
