well i have amp up and running somewhat. With only 2 watts in, had a 500 carrier out. input is stillaround 2.1 so i stillhave some work to do. alsorear left tube when i loaded up amp and just barely touched plate tuner, it arced internally. Also have another problem. using a foot pedal, but when i unkeyed radio, amp was still putting out power. Sounds like an oscillation problem. First want to get 4 new tubes and tune input better. What site areyou talking about. Could use afew pointers as to what is the best way to calm amp down some. Maybe better/ more bias to calm tubes. not sure as to what plate voltage is, so not sure as to where it is running.
