Hi friends

I find an interesting explanation about how to obtain Bias voltage without a bias dedicated winding and at the same time it gives a 15v/20v or more lower B+

this is the link http://www.aikenamps.com/BackBiasing.html

go to the tech info and read - What is "back-biasing"? -

there are other interesting stuffs to be read there
