The amp was stable for about 10 minutes then slowly the cathode current of the 6550 started to tick up, and then it picked up speed and i shut it down. I also put in a grid stopper on the input/driver tube. I put the ferrite bead on the wire lead to the grid stopper. it is short not even 2". Maybe i should go with a shielded input wire? The run is short as i said.
