A single 3-1000Z costs much more than a pair of 3-500Zs. 4-1000A tubes were once plentiful as broadcast pulls and were very popular in homebrew amps because you could get good ser; /archives//html/Amps/2006-05/msg00463.html (8,328 bytes)

BTI, and 2-3 others made ham amps with the 1000Z, and maybe 3-4 commercial amps had them. I have seen 1-2 RF Generators that used them.

Does it make sense that the improved version would have more feedback?
