I got a little time to put together the Texas Commander finally. It is already a bit outdated due to these latest advancements but people can see what an opamp driver would look like. I think there is a future for this style driver, just in a different form. The FET wound need to be mounted to the mcpcb to heat sinking for it to work properly but it is a very viable option for high powered drivers without some other linear components coming on the market.
