[Amps] Solid State HF High power linear amps

[R.Measures]

For sure, Steven - and 6 volts DC is an engineering challenge as well.  
As I understand it, when VW abandoned 6v in the mid-1960s, they almost 
went with a 24v system instead of 12v.  If they had done this, they 
would have saved much production cost on copper.
-  In its Prius gas-electric hybrid automobile, Toyota uses 200vDC.  
Now we're talking some real QRO-mobile.
