[AMRadio] Low Power AM?

Bob,

While the plate transformer may well handle that, you are tuning off 
resonance of the PI network.  That results in tuning off the Plate dip.  
I would NOT imagine that this concept would do the 6146s any good at all.

I would suspect that a reduction of Drive would be wiser.
