1. [Amps] Replace 2x 4-400 with 2x 3-500ZG (score: 1): Author: "Posselt Werner" <W.Posselt@maco.at>; Date: Fri, 2 Jun 2006 10:25:49 +0200; Hello! Is it possible to swap the 4-400s with two 3-500ZG without any further modification? The tubes are operating in grounded Grid configuration. The HV supply is homemade delivering 3,3KV.

Re: [Amps] Replace 2x 4-400 with 2x 3-500ZG (score: 1): Author: "Peter Voelpel" <df3kv@t-online.de>; Date: Fri, 2 Jun 2006 12:25:16 +0200; I usually do it the other way round as 4-400G/QB4/1100/RS1002A are more rugged then 3-500Z. You will get higher amplification, so perhaps 20% more output with the same driving power by using 3-500Z.; /archives//html/Amps/2006-06/msg00032.html (8,330 bytes)

My Henry 3K-A puts almost 4kV @ ~1A on my RF Parts 3-500ZGs, and I beat the tar out of 'em. They'll do 2.4kW output with 150W or so of drive. I run them with about 80W or so drive for; /archives//html/Amps/2006-06/msg00043.html (9,708 bytes)
