Redneck opamp

This is what happens when a redneck is curious as to how a opamp works. I googled opamp diagrams to grasp the internals of opamps, none of the diagrams would do anything on EC, even the ones with specific caps and resistors values. I had to make up a different concept based on just using the transistors to alternate the direction of current flow through the load. This concept is very successful in some areas, other areas not. Multiple designs created, most notable is I bridged two amps together to create a output of 6.1 volts open circuit off of a 6 volt supply.

I think @Voltransistor published a pretty good OpAmp model here. You'll have to do your own digging though.. X^)

I may be British, but I grew up watching Dukes of Hazard and helping fix old cars; I had to check this out. I haven't checked it all out yet, but I'm impressed already. It's the simplest decent op-amp I've seen on here, having the same component count as bryanthehacker's CMOS Op Amp, but his are all FETs.

Its just a h bridge amplifier. However i did recreate this recently to be a 3 terminal device like a opamp.

I took out the 500R, wired it with non-inverting feedback, and found it works fine. :) http://everycircuit.com/circuit/4966184301887488
