[Amps] Length of coax from xcvr to amp affecting input

[herzog]

Add to your considerations:
driving a grounded grid, or cathode driven ampflier will entail the 
final's harmonics traveling backwards through the coax to the driver.
This has caused me ANGUISH, and my ex-employer some of the million 
dollars that deleting a input pi tuner at the anps input saved, over 20 
years of my  studies of the problem and work arounds.
