RE: 813 triode connection

Posted by vinnie2 on April 21, 2017 at 04:30:42:
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.
