[Amps] 4-1000 amp

[Gene Bigham]

I remember building my first amplifier of significant power back in 1978.
It was the 4-1000 amp of ARRL handbooks gone by and Bill Orr handbooks.
It was a single tube amp but I used the 3-1000Z instead a huge jug of a glass tube.
I put a window in to see the tube in operation and it was absolutely beautiful to behold especially when making power.
The high voltage power supply was from a BC-610 minus the mercury vapor rectifiers that I replaced with solid state array and built into a plywood box that took two people to carry.
I sold that amplifier prior to leaving the Philippine Islands and wonder if it is still on the air today or not.
Anyway, I can understand the hams here talking about building amps with these huge glass tubes as they are quite pretty when operating.
