You have summed it up.

I'd be REAL QUICK *IF* you are going to do it that way.

Once you find the settings, mark them.

However, you'll find that you are fighting the tune-up procedures for 
the Apache in doing it like that.

The tune-up procedure in the Apache manual NEVER intended for the Apache 
to be tuned into an amplifier.  That's why it seems TOO simple.

Grid drive and all the other settings in the tune-up procedure are 
INTENDED to tune for the MAX output of the Apache.  They just don't take 
into account of that amplifier on the end of it.

You'll have to "Develop" your OWN tune-up procedures if you indeed feed 
it into an Amplifier.

Otherwise, you and the amplifier WILL have issues.

I'd never do it like that to my 3-500Zs.  They are the original ones 
that came with the LK-500ZB.  I am NOT in a hurry to replace honest to 
goodness Eimacs.
