Block diagram, the last stage to the far right (not shown) is just one more amp and output transformer.

Just basic info, I've got a full schematic as well but it's too grainy to make out any values. I'll hunt down a better quality copy of it.

Here is a quick correction to the side-chain showing how I believe the above F600 schematic should be.
This works in the simulator perfectly, but I can't guarantee this is how it is in the real thing as I don't have a real one.

This is the resolution to one of two corrections PRR noted here: http://groupdiy.com/index.php?topic=2070.msg27236#msg27236

I can additionally verify that as per the above post, the second correction to the output amp, which is far more obvious, is that the 3.3K resistor in the output amp has no connection to the collector of the NPN output transistor.
