300 Watt AM Amp Plans?

SRI, OM's,

I meant 300W _carrier_.   Should have been clearer.  Thought the mention 
of  usage w/TX-1 would be enough.

After thinking it all over, maybe I'll also look around for a HA-10...or 
some other "period amp" as a secondary thing until I can lay hands on an 
HA-10... ;)

Thanks for all the input!
