*whew* We agree on -something- ;-)
But I'm enjoying the discussion. I may not be the most
articulate individual around, and I'm -far- from reminding anyone
of someone whom posses articulatino, but when it comes to someone
saying "375w is the limit to run to get 1500w pep output", I
can't swallow that. It's a true statement, if you were to apply
a sine-wave (at an arbitrary rate... say, 1kc) to 100%, but as
it's been said before, we don't -talk- in sine-waves.
73 = Best Regards,
