I forgot to add, depending on the set/monitor, you might need to add a simple transistor amplifier to boost the signal a bit - the video amplifiers are going to be expecting a 5v signal level, and you're going to send an analog signal - IIRC, 1v p-to-p. You get acceptable brightness in most cases though, I forget how I dealt with it on the IBM monitor, but I know I had it producing a good picture.
