This is my first 811 Single Ended project, based on Shishido 811-A design. It is a typical direct heated SE amplifier using the svetlana SV811-3 power tube. It utilizes an interstage transformer for coupling between the driver and the power stage.
The schematics and more details regarding this project are published in my web site :
