Bill,
I can replace the tube(s) in my amp fairy easily, and driving a
1000+ watt amp at 100 watts is just loafing it. However, I can't
replace the finals in my PROIII (I have one too.) I'd have to send
it back to the factory, or find a local electronics guru who was
willing and able to do it for me.
My philosophy after 23+ years on HF is to let the amp do the
work and save the exciter for this reason. In my view it is better
to have the amp and rig both running at 10-15% capacity than to have
either running at or near 100% capacity.
