I finally finished the Zenith 6S222 and would like to share my project. I picked up this Zenith 6S222 at the 2009 Kutztown show and did buy those feet from the 5S218 which fit fine. This link shows the progress:

The original chassis had been worked on some time before but it still needed a though cleaning, cap replacement, and alignment. Also the dial was in great shape but I fabricated new pilot light shades and repainted the white dial enclosure as it had yellowed. The cabinet was in very good shape other than yellowed scratched lacquer. It only needed stripping, sanding, and a very light mahogany stain on the end strips to bring out the color. I decided to make the edge trim a dark brown for contrast, which may or may not be original but it is what I wanted.
The finish is six coats of Mohawk clear lacquer, wet sanded with 2000 grit paper, and polished with 3M hand glaze. Lastly a friend had a large can of 40 year old of Butchers wax which I applied two coats of. The speaker is not original but is at least a period electrodynamic Jenson, and the output transformer was burned up so I got a 7K primary impedance type from Edcor transformers. They custom make transformers and are half the price of Hammond.
Lastly the radio came with the loop antenna shown which is from another probably newer Zenith but it fits and works great so I left it installed.
My next project is a Sonora RCU-208 which seems complete but in a bit worse condition than the Zenith, followed by a Philco 600, a Philco 42-321, and a Silvertone 1671.
Thanks,
