The old Zenith stuff of this era is nice, because they used almost exclusively disc caps, which means if it doesnt work, all it needs is the power caps (and one more in the tone section usually). What that translates to, is it usually works out of the box.
Yes! It needed a new speaker and the clock motor needed lubrication, but I also added the polarized cord and moved the switch to the hot side. It has the floating chassis, but it's not very isolated from the external metal case (just some cardboard).
Like many of these it uses a "couplet" (early IC) for the audio inter-stage coupling.
All of mine are plastic or wood cased, so I've not bothered with the polarized cord. I also use vintage coffee makers (percolators) that have significant leakage out the chassis.

It's brown if anyone is curious.
