Phil,

That's true. I have seen some built though that has a low power using 1/2 plate voltage and those pretty much needs to be retuned too. Of course thats changing the plate voltage not power input. If it's legal to run 1500 watts and the amp does it, and you need the 1500 watts to talk, you have it, use it.

Best,

Will
