[Boatanchors] 6AG7 160 meter rag chew ideas needed

[David Stinson]

If you want your rig to work acceptably and stay on freq, 
"simple" and "no crystals" are mutually exclusive.
Without extensive temperature compensation and carefully
selected components,  a "simple" LC power oscillator 
isn't going to stay on freq and will FM with modulation.
At this power level, Bry's crystals should work well.

Carbon element in the cathode will work and saves parts
and money.
