Earlier quoted context omitted.
Does it work? (I hope it does!)
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.
