[AMPS] Purpose of CW/SSB switch

[DavidC]

> What is the true purpose of the CW/SSB switch on many of the older linear
amps ?
> Was it simply to ensure that you stayed within the old power INPUT
regulations when in CW mode, or is there some other good technical reason ?
>  Obviously the reason I'm asking is that I can't see a good technical
reason for the switch.  Actually I see good reasons for not having it but I
need someone to verify my understanding.  (I wasn't planning on having one
on the 4-1000 amp I'm building).

Phil:  I am sure the experts here will respond, but as I understand things
the bias needs to be changed for best linearity for each mode.  You *may*
also have power-level adjustments as well, depending on the amp I suppose.
