Just went to old radio dude place today, and picked up a pair of 803's and
a pair of 866A's. Also he gave me a gigantic transmitter coil form. The
thing is at least 6" diam. and 12" tall. Even has a primary form with
ceramic insulators. May make a nice form for the tube coil I am building.
My question is: He mentioned seeing 803's in a push-pull circuit being run
at 2000W, but I only show the max plate disipation as 125W. He says its
possible, but they glow red hot.
