[Amps] Ten Tec Titan 425

[doug ferguson]

Thanks for the suggestions.  I’ll look at the coax and path to the tubes.  As for the degradation of the tube(s), I get full output
with exactly the same drive, about 50w on 40m, as I’ve always gotten, so if it is an emission weakness it doesn’t effect output
at all.
As for putting 100w through it when off, Guilty!  Not very often as I don’t often need that much power for high duty cycle modes
But have done it, I’m sure.  What in the amp could that damage?  I’ve not been able to find a stat in the manual for how much power
It can handle in “pass through” mode.  I only would have done it when turned off and only found a referenct to how power is routed
from the exciter when the Amp is off.

I’ve had the Amp over 20 years and as far as I know it’s got the original Eimacs in it, certainly not Chinese changeouts but that’s good
to know if I ever do change tubes.  I’ve been extremely careful with grid current, etc., over the years and it’s rewarded me with great
performance and the K3 tuner does the trick but not sure how this SWR issue might affect it long term. It doesn’t seem to be getting
any worse although as I said, it’s very slowly changing and I first noticed it a couple years ago.
