I've had one of these radios in restoration for 2 years, and as a birthday present to myself,I just spent the weekend scraping, steel wooling, and refinishing the cabinet. It's 100% back together and playing like nobody's business now, I have to say these are really fine sets. I had a model 680 which was tops, but this one is as good I believe. The chassis had been playing on the workbench for quite a while. The intersting scare I had after putting it all together, was no sound and smoke!! I traced a 1000 ohm path from B+ to chassis out to the area around the Fidelity-Selectivity/AFC part of the chassis. It turned out to be some conducting debris/dirt/bits of wire or other stuff that got around a 6K7 tube base; once I pulled the tube and reinserted it, the short went away, and the radio played fine again. All I can say is that these chassis are not getting any cleaner by themselves.
