I have a question about the plate efficiency of a GS-35b amplifier. I have built two of them for 160-10 meters, and while they worked ok, the efficiency was not as good as I expected. In both cases I
I see you found pragmatism (real-world) trumps "specs". My in-use 6m GS35b is 55% efficient, measured "old method" with 4400vdc on the plate & <150-vdc drop full-load. 57% (including power added), wi
And I'd like to hear more about expectations of what a single GS-35B will do under in-spec operating conditions. Bill's numbers are in-spec at the edge of the published limits. My question has to do
if you can get hold of VK3ZL I know he's recently built a GS35 amp and did a very professional job of it, so he'll no doubt have some answers cheers Dave G0OIL And I'd like to hear more about expecta

Perhaps an 'elite class' solid-state amp will appear somewhere on the market? http://www.thp.co.jp/english/hl_2.5kfx_e.html Paul (KG7HF) _______________________________________________ Amps mailing l
I looked at the Tokyo Amp but was turned off by the fact that it is quite sensitive to SWR (1.8 Max) and the Finals are not well protected. 73, Dick, W1KSZ ___________________________________________

Thanks to those that replied with the "Prometheus". Whatever the reason, it hadn't grabbed my attention until now. I'll do a little investigation, but at first glance I didn't see any review referenc

Thanks, and it does help. I haven't built the power supplies at all yet, so it isn't to late to turn back at all, but I probably won't. The whole topic though really just made me wonder if there are
Maybe, maybe not. But it will surely lighten your wallet !! 73, Dick, W1KSZ _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/l
Jim, I saw one of those amps at Dayton. You will need 3 strong men and 2 boys to carry it. Not sure about the control board part count - agree 1K parts seems quite a few - but the overall build quali
Speaking of GS-35b efficiency, What is the efficiency of a pair of 3-500z's?? Say in a HL-2K Mike KC7NOA Hotmail: Powerful Free email with security by Microsoft. Get it now. _________________________

Yes, K0RU (a psycho high-speed CW op) and I were standing there looking at it. I'd not seen a contempary Alpha and wanted to see "how the big boys do it." While we were standing there, wondering why
