Sometimes I get excited about my latest circuit and after looking for just the right tubes, output transformers, coupling caps, and low noise resistors, the power supply design becomes almost an after thought.
Sometimes things turn out ok and there are no problems. The truth is, there is no reason to suffer power supply set backs like this. The design of basic tube power supplies is actually very straight forward. What I’d like to do here is to walk through a design process first recommended by O.
Schade1 in 1943 and presented in a slightly modified version by Herbert Reich2 in 1944 in his book “Theory and Applications of Electron Tubes”. Now, the state of electronics has changed somewhat in the 67 years since Schade first published his landmark work. As such, I will present again, a somewhat modified version of this process more suited to today’s amp builders and hobbyists. I am going to work through the procedure by designing a supply for a mythical low power stereo amplifier. It’s a stereo single ended class A design I’ll refer to as the Ghost amp. I will first present the process for each step and then fill in some numbers to show how the process works. I urge readers to read the entire design process first and then go back and look closely at the math.
