With TV stations shifting to digital, how would a surplus analog 
video distribution amplifier do?

There should be a lot of high end amplifiers made by Grass Valley 
(Tektronix) available soon.

These are used in a frame. The input loops through the frame. Each 
amplifier has 6 isolated outputs. Depending on the amplifier, you 
might have control over the equalization or not. All that I have seen 
allow the amplifier gain to be adjusted from the front of the module.
