Willie and John,
I believe that the simulation works for the QDX version of the amp.? I'm unsure about the EER/power addition of the QMX.? That may be more of an issue when Hans offers the SSB upgrade for the QMX.?
Zener protection has been put on CW and Digital mode radios.? I have not seen it for SSB, though that does not mean it is not a common practice.? I do not have an extensive history with higher-power SSB construction.? Most have been at QRP? or under 20 watt levels.
Regardless, actual measuring is always better for an individual rig.
