I saw that video you speak of and for tbe most part I agree with you. Basically they want it for bragging rights and because they want to talk AT people not WITH them. Now having said that there are others that want a 3CX3000A7 amplifier because it will loaf at full legal limit regardless of mode. Henry made the 5K and 8K models with that tube and it was a legal ham amp. There are several home brew 3CX3000A7 amps on the ham bands running pretty much legal limit .........yes that is true.......because in grounded grid service that tube is hard pressed to make 2Kw with 5000 volts on it when driven by a typical 100 watt transmitter.Increase drive to 300-400 watts and you will see an easy 5-6Kw from it. I myself am currently working on an all-band amp using exactly this tube......a 3CX3000A7.I have several freebies that were in broadcast service and are working pulls along with a pair of good sockets and several blowers. It would actually cost me more to go with a pair of 3-500Z's LOL. All I want is my Canadian legal limit of 2250 watts or a 750 watt carrier plus modulation on those long winter nights for 80m AM.
