Gordon,
Understood, but you are describing concerns about "power consumption" which just part of the "power efficiency" calculation.
I've heard people talk about consumption all the time, but not couched in terms of "efficiency" per se.
Thanks,
Ken, N2VIP

Ken, anybody who¡¯s having to work off batteries thinks this way. It¡¯s a very important parameter to them.
I suspect the people who pay the light bill for 50 kW transmitters also think this way; but I don¡¯t know that for sure.
When you¡¯re trying to figure out if you can run that amplifier on that circuit or if you¡¯re going to need to put in a 220 V circuit you think that way also
It can be difficult to figure out the actual efficiency of the final stage, but it¡¯s not hard at all to come up with the overall efficiency
It¡¯s one of the things that people in my neck of the woods have complained about some radios!!
