Well, OK, Ron. I finally got the 37-650 chassis yesterday, that I bought off of eBay. Tubes were with it, so that's good. Speaker also with it, with another open output transformer........! Dial scale has a crack in it, probably from shipping damage. I will cement the crack together with speaker cement. It's still usable. Believe it or not, the tuner mounting grommets are still good as new.
This chassis was almost totally unmolested, the only obvious repair having been a filter condenser replacement some time ago. The speaker harness is there. I'll need to replace the little pin plugs on each wire.
This chassis will replace the chassis in the phono combination. It'll be a matter of re-capping the chassis, re-aligning it, and into the phono cabinet it'll go. The chassis in the phono set has had all sorts of stuff scrawled all over it, and the speaker harness missing. If at all, that will become the "parts chassis".
NOW, RON: I gots a question. On the 37-650 chassis, the 5Y4 tube sits atop the power transformer, as on many Philco sets of that vintage. I've never tried it, but if I pinch the little protrusions on the rectifier socket, will that cap on top there come loose, and let the socket in the open? If so, I can install the jumper links on the socket, and make it work with a 5Y3 OR a 5Y4. I have lots of 5Y3's, so it could be handy.
What do you know about the accessability of that socket?
