Sort of. It all started with Willie's 26/26/45 SE amp (which I built and still have) and then I decided to try the same idea with the 845, but try to use sukumos idea of an 845 driving an 845 and ended up using the 813 instead. I also wanted a low voltage amp as I don't like playing with high voltages. The design is not a formal one, trial and error mostly. If you look at Mikey's last post above, my 813's are connected the same as the one on the upper right in his schem except for pin 3 beginning also connected to the plate via a 200 ohm resistor.

That input connection is correct.
The signal is applied to G1 (pin 4), not G2 (pin 3).

"Still Working the Problem"
Checked the breadboard and it is wired correctly. I think I must have redrawn the schem at one time to clean it up and labeled it incorrectly. I am going to go back before I do anymore building work and redraw the schem based on the breadboard and post it. Hopefully you guys can tell me if you see anything else that looks incorrect. Thanks for the help!

Dang! I was looking at the wrong number. It's labeled kind of funny. Now I will have to go take a really close look at how I actually have it wired up and see what I have for sure.
