Hi Skipp,

I have a serious question, and I think the answer would be of great 
use to many people.

Can you share the formula you use in determining the amount of L 
and R required to stabilize an amplifier?

I can use a series of measurements to determine the approximate 
value of R and L in most cases, but I've also found many cases 
that require testing of several PA's to optimize suppression. A 
simple formula would certainly save work!
