This is the 17A1 schematic from Wallace-Telaides:

The set I have is a 17T1 chassis. There were relatively few of these made compared to the 19A1 chassis. They're very similar, but the 17T1 has some additional circuits and some production changes. The catch is that the previous restorer probably used a 19A1 schematic. Apparently they knew what they were was doing. It's a sloppy restoration, but it worked when I got it. I'm trying to replicate what the previous restorer did.

Here's another link that may be helpful. It's the 17T1 schematic overlaid on a 19A1 schematic. Printing that's only black (not black with red overprint) indicates a difference between the two chassis.

Thanks for the tip about an analog meter. It never occurred to me that they still made those.
