Pardon my ignorance, but I was under the impression that we, as hams, are entitled to a maximum of 1500W input power; maybe 2000W or so in the States. What is all the talk on the monster transformers

The point I was making is that - for solid technical reasons - the "headline" kVA rating of the transformer needs to be significantly higher than the DC input to the amplifier, which in turn needs to
