thoughts on ways to adjust power to amp

Ok I see your point on the signal being overloaded from real channel 28. I have wondered if you or anyone else for that matter have ever tried using a variac on the power supply to the antenna preamp? I tried using it on the televes setup that I have and really don't see a drop in signal strength until I adjust it to 50 volts ac or less. I do have some adjustment on signal strength after that. I am not sure if this is because the voltage regulator in power supply is compensating for the low voltage and it quits functioning when volts fall below 50 or what. AGC circuit? I would like to try it on a titan 2 or something in that type of amp just for grins.. I think a truly adjustable amp gain at the antenna could be usefull...maybe maybe not??? THOUGHTS?
