1. [Amps] Ten Tec Titan 425 (score: 1): Author: doug ferguson <thenewt@msn.com>; Date: Tue, 15 Dec 2020 21:47:31 +0000; I have a Titan amp that has over time, presented an increasing SWR to my Elecraft K3S. I have a SteppIR beam so it appears to be an input network problem in the Amp. I use the tuner in the K3 and all; /archives//html/Amps/2020-12/msg00024.html (7,047 bytes)

Re: [Amps] Ten Tec Titan 425 (score: 1): Author: gudguyham--- via Amps <amps@contesting.com>; Date: Tue, 15 Dec 2020 22:11:02 +0000 (UTC); Input swr can fluctuate on grounded grid amps when the emission of one or more tubes goes down. In your case I agree its unlikely that every band would show increased input swr at the same time beca; /archives//html/Amps/2020-12/msg00026.html (9,277 bytes)

Re: [Amps] Ten Tec Titan 425 (score: 1): Author: Mark Robinson <markrob@mindspring.com>; Date: Tue, 15 Dec 2020 17:36:52 -0500; On my 425 the input swr has changed dramatically with different Chinese replacement tubes. The original EIMAC's presented a very low swr on all bands. Now with the Chinese replacements I am using a m; /archives//html/Amps/2020-12/msg00027.html (8,718 bytes)

As for the degradation of the tube(s), I get full output with exactly the same drive, about 50w on 40m, as Ive always gotten, s; /archives//html/Amps/2020-12/msg00032.html (8,647 bytes)

Youll notice if you try to use a foot pedal for example to key the amp and you have the radio feeding a signal in before you switch th; /archives//html/Amps/2020-12/msg00034.html (10,591 bytes)

While this circuit is documented in the set of schematics that are part of the manual, the split of this circuitry across multiple pages describing each circuit board makes it tricky to follow.; /archives//html/Amps/2020-12/msg00045.html (8,349 bytes)
