What does the amp show for output when driven into a Dummy Load?
I would run that test next, before I started buying new tubes/etc.
Spend some time doing a bit of troubleshooting to find the problem.

Subject: [TenTec] Low output on Centruion after lightning
I have a Centurion about 6 years old that has always made around 1200-1300
watts on all hf bands except about 1000 on 10 meters. I recently had a
lightning strike to my fiberglass dual band vhf uhf antenna on a different
tower from my hf antennas and neither of my hf transceivers were damaged.
I now find that I can only get about 700 watts on any band driving the amp
with either transceiver. Could this have damaged the tubes? I don't mind
a new pair of 3-500's if that will fix the problem. Should I buy the
regular 3-500z tubes or the zg graphite models. Will I gain anything by
using the graphite plate tubes? Any mods anyone can recommend that will
improve the amp performance while I am in there? Suggestions please!
