Hello All, I have an 820S that I can't seem to tune up properly. I can't get a plate current dip, and when I tune for max between the plate and load, the plate current runs away and blows the fuse. I changed all the tubes, checked the caps, resoldered all the connections in the final. Happens mainly on the 80m band. Anybody have a similar problem that they solved? Thanks, Walt, w3fnz
