Original poster: "Gregory Peters by way of Terry Fritz <teslalist-at-qwest-dot-net>" <s371034-at-student.uq.edu.au> Hello all, I can get some near new 4-1000 valves pretty cheaply. These are a 3kW rated transmitting tetrode. How would these go in a VTTC? What configuration should I use (should I wire the screen and grid together and use as a triode)? Cheers, Greg.
