Arent Class E monoband amps and pretty much with a 7 MHz upper limit?
At least that was what I was told by an active E builder who had a 400W 75M
AM amp inside about a 17 x 12 x 3 chassis minus the PS. I was impressed but
I still like the glow of my 250TH's and 304TL's ! Even tho it takes up a lot
of space and weighs a ton.
