Greetings. I have a TENTEC Centurion (pair of 3-500Z) that has worked
great for several years. Used it this weekend to work the H40 on
RTTY. Although I worked the H40, the amp started arcing (because of
operator error/wrong antenna/you name it!). Anyway, now when I drive
the amp to full power with correct load, it arcs - all bands. It
looks like the arcing is in the big tuning capacitor. It sounds like
a spark-gap transmitter. It does it whenever I drive it over 400W. I
haven't opened it up yet, so want to get some ideas of what to look
for, and possible repair ideas.
