1. [Amps] GS-35b 2 meter amp - plate capacitor spacing from tube? (score: 1): Author: Bill Dzurilla <billdz.geo@yahoo.com>; Date: Thu, 10 Jun 2010 13:53:49 -0700 (PDT); Any Russian tube experts on this board? Picked up a homebrew GS-35B 2 meter amp, seems to be working OK, about 650 watts out with 50 watts drive from my FT-847. The anode is tuned with a piece of cop; /archives//html/Amps/2010-06/msg00116.html (7,420 bytes)

To match a higher impedance requires less coupling C. Less coupling C means you need more tune C to keep the plate circuit; /archives//html/Amps/2010-06/msg00118.html (8,172 bytes)

(score: 1): Author: "Thomas Hoeppe" <thomas.hoeppe@asamnet.de>; Date: Fri, 11 Jun 2010 05:36:00 +0200; Hello Bill and Gerald, it is also possible that the load C is at a low value. In that case you need more C on the plate. Often, only C plate can be reached from the front, while C load is inside....a; /archives//html/Amps/2010-06/msg00119.html (10,162 bytes)

I was able to extend the plunger, and output increased to 850 watts, with 50 watts drive. And I was able to find a dip. The only thing that seems odd is that the plate curr; /archives//html/Amps/2010-06/msg00125.html (10,200 bytes)
