Zenith "Graemere" porthole scored

[bandersen]

I picked up this Zenith G2346R 12" porthole set a couple days ago just across the Wisconsin border.
The cabinet appears to has identical styling to my 16" Monroe set, but it's 20% or so smaller.
I plan to restore both, but one will have to go after that.



Missing a few small knobs.


I pulled a few tubes and found numbers like 19BG6 and 25AX4 so I figure it must be a series wired set, but what's that huge transformer for then ?
I dug up a schematic and found that it is indeed a series filament hot chassis set, but the B+ and 5U4 are power by that big transformer.

The label inside indicates this model came with either a metal cone 12UP4A or an all glass 12LP4A. This has the 12LP4A and it appears to be original.
It has a wacky ion trap magnet composed of two magnet rings mounted on a brass sleeve.


The flyback looks to be in decent condition. The seller claims he powered the set up and got a raster with about two inches of vertical height.

I tried testing the CRT but had trouble with intermittent contacts in the loose base. The readings I did managed to get were deep in the bad zone though
I'll unwrap the electrical tape holding it on and try to fix it up.




I'm inclined to keep this smaller porthole set, but the 16" is more impressive and does not have a hot chassis

The seller also had an Admiral 16R12 for $10 with the original metal back and intact pencil box door so how could I refuse

I did a little research and found out the the brown bakelite set is the 16R12 and the black version is the 16R11.
