Hello
The goal is to change an old HP test inst.power.The transformer as one output with a middle tapeNOT wired on Ground.It give about 36vDC.This is regulated by 2N3055 and give Vout of 26v.FloatingThen this 26v are splitted in a +20v 4A ajustable and a -6.3V 1A,measured to ground(ground is catched on a serie -6.3v transistor.
This power is defect,and as it contains numerous TR and Zener I want to use todays regulators as LM317 or 350..How do Idesign this floatind power splitted into these 2 power?Thanks
