In Reply to: "Which stands for shunt regulated push pull" posted by Allen Wright on September 20, 2006 at 03:09:12:
I once did a little small circuit analysis of the SRPP. When you do this the top rail becomes grounded as does the bottom end. There are thus two AC generators in parallel in this model with respect to the center connected output. Two generators in parallel are in shunt. Together they push and pull out of phase. Now how this is exactly "regulated" I don't really know.OTOH, the inputs to these parallel generators are actually in series. Because of this, some will argue they are series connected. The odd thing is that the output is between the generators, operating in shunt push-pull, but the inputs are definitely in series. It's an unusual circuit.
So this circuit might as well be called anything you like to focus on. I just say SRPP and never mention what that stands for. :)
BTW, the gain of an SRPP is about half the mu of the triode, in this case about 10 per stage. So the overall gain is 100. That's a pretty good gain to drive the 845 from line level.
