I did hook up an old VCR/DVD combo with a built in RF output and was able to get a blurry picture..so that's good news.

Any hints on where I can find a 1200 OHM 25 watt ceramic rheostat with a long shaft? The Clarostat part number is RTV-220.

Photo soon...
Yup. Surplus Sales of Nebraska.

There's a 1k 25w and a 1.5k ?w on this page:

Focus Controls are a soft spot on these old DuMonts.
