  1. The higher voltage op amps i've see are pretty expensive. Wonder if you could incorporate a circuit in it to bring the vcc down to 12v. and still have it work. If the circuit works right I was wondering if you could add some pass transistors and some 10 watt or so emitter resistors to the output.
  2. Dont mean to resurrect a dead horse but I recently came across the old stabilized o-30 volt power supply. I found the original magazine article from 1978. Seems like it lost it's original design over the years. I attached the pdf of the issue. It starts on page 40. Practical-Electronics-1978-10.pdf
  3. Is anyone still working on this psu or has it been determined to be a dead horse.
