  • Looks interesting.
    Can you explain a little more about this project (schematic, power source...).
    Thank you.

  • The project I found on the internet googling "6n28b tube circuits" - then I did few modifications on the power inverter stage (34v). The power source is a 1 amp small PSU that I´ve found on a electronic store plus a combined electrolytics of plus 10.000 microfarads. The power consuptions is about 530 milliamps.
