Looking for Info About Early Transistor Mixers and Mic Pres

It is because with an inductor load, the collector (or plate for that matter) can swing up as high as twice  the supply voltage. That is twice the range of a resistor loaded stage hence four times the power because power is proportional to V squared. 

Thanks Ian  
Sometimes I can't see the wood for the trees  ??? 
I was stuck up my particular tree thinking only about double  voltage swings.

Inductor has low resistance proportional to impedance.  Little DC voltage divider loss, unlike resistor.

Well, since nobody has mentioned them, the Germans had some very nice transistor designs as well.  Also made to replace tube pieces, so they use lots of transformers and other costly bits like rotary switches, inductors, etc.  Tons of schematics at http://audio.kubarth.com/rundfunk/index.cgi
