I think your right on that assumption also there isn't any DC high voltage on the plate or loading caps or shouldn't be if the plate blocking cap is good. What would cause the loading cap to arc is that the tank coil has too much or not enough inductance also once the plate or loading caps arc you could try and file or sand down the burrs but sometimes after their damaged they'll keep on arcing even with right inductance.nutcracker wrote: This amp was suppose to be setup for 11 meters but im not sure at this point but the tank coil just dosent look right either. I didnt even think there was suppose to be high voltage on the capacitor plates I am starting to think it was not properly modified for 11m

If that capacitor has arced, one of the 'cures' is to polish out the pits caused by that arching, which can mean disassembling that capacitor. Certainly possible with some, impossible with others.
Unless that capacitor 'lives' in a really dirty environment, the typical way to stop that arching is to lower the applied circuit voltage. Don't 'push' the 'fire' out of it (pun intended).
Happy thought, huh?

The HV relay had a hairline crack in it, and it caused high voltage to jump from one leg to the other and made my amp do the same thing. Inspect your relays with a magnifying glass thoroughly, and make sure they aren't pitted or that the plastic isn't cracked. The center relay is suceptable to this, and it's very common due to the fact that ALL the amps power goes through that one relay in the center of the chassis. Be sure to discharge the caps before fooling around inside one of these, but i'm sure you already know this. I've been electricuted many times! Let me know what you find, i'm almost posotive that might be your problem.
