I will make my circuit suggestion how to use the LME49830 mosfet driver.
I want to keep this amplifier easy to build.
So, will be simple & good 🙂
My starting point is the typical example from this Application Note
by National Semiconductors laboratory workers and designers.

Here we go.
Your own suggestions & corrections are very welcome, as my work will progress.
I will start with Version 1a, using these:

An externally hosted image should be here but it was not working when we last tested it.
The Basic start Schematic
here is attached
the basic circuit recommended by National
I will add components after doing research using my Professional Spice Simulator.
This will be my main tool to evaluate, initially.
You may do the same, if you know & have a spice sim.

Hi Lineup,
have you considered using 9140 and 240 as a nearly matched pair?
Limits the supply to +-50V, but can still give adequate power

240 and 9140
Are they known to good match complementary ?
I know sometimes best choice does not follow numbers.
Something about Rds match maybe ?
If you give a reason and some detail, Andrew, I'll look into this

some amp builders on this Forum recommend 240/9140 combination.
Ampguru offers his amps with this as the low voltage option.
It appears that the 9240 is a poor complement to it's numerical partner and this is a very common problem with most vFETs.
