[Amps] "10 Meter Ban" to be lifted ...

[Bill Fuqua]

Not that anyone on the list would really care, but running two tubes at 
legal limit should reduce
the IMD products (Splatter) if they were biased correctly. Lower efficiency 
but cleaner signal.
Naturally, your transceiver would have to have reasonable IMD to take full 
benefit of this.
