[AMRadio] what is this????

[Jim in Waco WB5OXQ]

There are suckers born every minute.  A pair of 3-500s will make 800 watts 
with about 70 watts in!  Notice down the way they show a chart where more 
drive will produce several kw.  I was under the impression that you cannot 
drive the 3-500s with much more than 100 watts.  I really believe this is 
pure junk.  Ceramic tubes can produce a lot more power simply and require 
less drive.  CB'ers don't know how to build an amp correctly.  RF engineers 
excepted.
I expect a single 3cx800 can make that much power with 40 watts drive.  Want 
more with a single tube use a 3cx1500.  In my opinion using that many tubes 
is very inefficient.
