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!
