With predistortion coming sooner or later to mainstream radios, higher PA voltage for 100W is dead issue. Ignacy
Higher voltage PA and predistortion are completely separate items. Even with predistortion, good engineering principles mean higher voltage transistors one should be used for 100W class rigs. Most 50 or 60 W "12V" transistors are class C devices (a pair for "100 W") ... predistortion is not going to make class C finals clean enough for reasonable SSB. Modern "12V" radios are 10 dB or more dirtier than older generation tube transceivers. 73, ...
