[Johnson] Another Valiant Newby question

Why would you want to drive a Thunderbolt with a Valiant? There's no real
output power advantage other than drawing a lot more current out of your
incoming AC line. The slight increase in power output using this combo
probably wouldn't be noticed at a distant receiver. However, driving it
with a Ranger or Ranger II, or anything around 10 to 50 watts, would make
a difference at the distant receiver. A Valiant driving a Thunderbolt, or
any other high power amplifier in the AM mode, is a waste of time and
effort.

I you want a stronger signal, work on the antenna.
