[Amps] How to tune an FL-2100B

Thanks for the nice reply, Tom....

goody....scratch that idea....

Why can't I just reduce the drive on the '101 to 25 watts and drive 
the amp with that?

 From brief experience:

It looks like if I drive the amp with 25 watts, I get around 125 -130 
watts out of the
amp. Four times that (PEP) is 520 watts, well below the 1200 watts PEP rating
of the amp.

What am I missing here?

I see....
