Some time ago (maybe 2 years) there were comments filed on this site regarding
increasing the efficiency of the 813 tube on 21 - 28 mhz. I've looked through
my history of this group but failed to find a reference. I also checked some
GE Ham News articles that I've saved. I realize the tube wasn't designed for
this spectrum. However, I do seem to recall some references being made on this
site based upon personal experiences. I really don't intend to waste the
groups time, but I sure would appreciate any circuit suggestions that would
lead to increased efficiency of this tube.
