So I saw a post by a local guy giving away an old TV for free. He was told it worked the last time it had been powered up about 20 years ago. I got it yesterday, plugged it in and twiddled the knobs for a bit to get this showing (300K JPEG) on the tube. It looks ok, but it seems that the intelace isn't working. THe bright bar at the bottom of the imageis a squshed version of the above, leading me to thing that the set isn't sweeping back to draw the interlaced image. Anyone know if a 1958 set would do interlacing, or know more about tube/valve electronics to diagnose it? Other than that the set tunes to the local stations fine and the sound is almost perfect. I wouldn't expect tube generated sound through an 8-10" speaker to be nearly as tinny as the modern sets I have with pairs of 3" speakers. That one big speaker has great bass.
The TV is a Zenith C2358W w/ chassis 18C20 ca. 1958.
