I think not using ALC is fine, if and only if, you know how to manually set
the drive level to a point that is appropriate to your amp, and if you do
this all the time.
If your amp will accept the full output of your exciter without being
overdriven or anything, then you don't even have to worry about that.
You just set the drive so as to get the amount of output you desire.
(I'm intentionally ignoring tune up of the amp...which obviously has to be
done too)
