Seems that the old motracs put out about 30 watts with a single 6146 driven by
a 6146.  Higher powered units ran 5894's and zippy amperex variations on the
5894 theme with outputs in the 80-110 watt range if memory serves.  I think a
pair of 6146s could do somewhat better than 40 watts on 150 mhz?  but I've been
wrong before.
