CTC-4 Director 21

[Phil Nelson]

Regarding a video preamp, I just updated my CTC-4 article with a new section at the end, describing what I built:

My preamp didn't work, due in part to a wiring mistake. I fixed that and messed around a little more, and then pushed the whole thing aside because I was burned out on the project.

Anyhow, I have to believe that the basic design, taken from the 1956 article in RCA Broadcast News, will work if someone takes the time to build it correctly.
