In class A, the 3rd harmonic content is somewhat less, and the higher order
products are way down. Without that feature enabled (the usual AB), the 3rd
is stronger and all of the usual higher order products are present and
strong. I normally drive my Alpha 76PA with the 5K in class A at about 60W.
The output signal is nice and crisp with that combo.

Subject: [Amps] Why not use the ORANGE button?
I see extoling comments re K3 clean xmitter. What about the Yaesu
transceivers with the ORANGE button (some call it red)? Any Yaesu owner has
stepped up to the plate and said he just uses his orange button on (ALWAYS
at full power, max RF power knob fully clockwise).... and explains and
extolls that strategy to put out cleaner signals???
Someone, please just state how much the orange button Yaesu-s help,
preferably compared to the K3.
Thanks mucho,
73, Charly
