Matter of fact, I got the emitter follower idea out of the Motorola book in one of the application notes. Might have been from one of heldges amp plans/diagrams. I just added a few things to basic design. I think his was for a very well regulated PS with no voltage drop under load. I actually use something lower than 12 volts with at least a 3 amp rating and higher wattage rating to account for heat due to much higher voltage drop. Actually if you look at some of the Joker Amplifers, that is were I got my idea/start from.
