AHHH...lost the raster. I had it almost completely buttoned up and I decided to watch it again. Had raster, no picture, had audio. Looked on the back and found the green wire disconnected from the neck connector and the bridge on the horizontal outputs had disconnected on one side (must have bumped it). I connected the wire and the bridge thing back up and had no raster. Disconnected the green wire and raster came back. Changed the connector with the one off the other DuMont, same pins and color code. Now no raster whether the wire is connected or not. I tested every tube associated with the horizontal section and they all tested good. HV seems fine from the spark I get when I discharge it. Picture tube heater is working. ??????????????????
