More pictures, tube regs are fun

Heres another picture, friend got it to work.



Works well, without any filtering in the supply output noise is measured at around 2mV RMS into a 150mA constant load. With about 5VRMS ripple in.


Could have been better, i designed in a Zener reference that is noisier than a VR tube such as the 85A2
