Let's repair a High Voltage power supply designed by Heathkit. This IP-32 power supply will make over 400 Volts, with a bias and filament supply as well. We will look at the schematic, and I will explain (with a demonstration) showing you how it functions.

  • I wish the Heathkit company was still around. I would love to build these projects daily. Thanks for the video.

    Mr. C, thanks for explaining the dual feedback voltages on V3, the 6BH6 control tube. You did a great job.
  • I, as a young lad once surprised myself with a cheap broken camera. The flash unit cap was charged and upon touching it, I threw it to the opposing wall and jumped back a good length too. When I went to inspect, it still held about 300V. Didn't expect that from a device that took 3 AA batteries, but I got wiser quick.
  • Well if you are into electronics it doesn't get much better than this channel,truly excellent!!

    Another excellent teaching video! I am proud to support you on Patreon! If I have any complaint at all, I can watch the video in the run time, in this case, 58.42 minutes with the result of WANTING MORE LOL! I have made a few videos and know just HOW MUCH time it takes to film, edit and produce a video so I understand the time factor! Again, thank you for the huge effort it takes to produce these for us!

    Hello, great video! I finally figured out how you find all your minty fresh vintage gear; you arrived here on a spacecraft powered by a VTWD - Vacuum Tube Warp Drive - so obviously you have a time machine to go back and find the best vintage kit. I also now know who REALLY invented the internet. But not to worry, your secret is safe with me. ;)

    Hi Paul, have you ever thought of placing a small, long lasting, label inside or outside of the devices you repair? "Restored to life. Mr Carlson, 2018" That sort of thing. It adds provenance and value. Graham (Australia)

    Paul, I had a rough day. Watching this video makes me feel relax again. Good explanations, great content.

    Rarely I can finish a movie or show or any type of related programs, regardless of having many sources to entertain my self, your videos are really easy to watch, learn new things and enjoy every moment of.

    Heathkit was great company. The staff really did care about their products and the assembly manuals were very well written.

    I am 62; ,this is the first time I've seen the innards (or even studied) a tube-based (regulated, variable) power supply! Great video, Paul.
  • "Chung", Soooo....those are out of there....Love it! Cheers to a great teacher :)
  • @octane613
    Your videos are so in-depth and well made. Extremely niche and intriguing, I could watch this all day
  • Another Hour well spent ! Big fan on both youtube and patreon . Thanks again for all the work you put into these video's Paul !
  • @MichaelLloyd
    Very nice. The detailed explanations are very much appreciated.
  • @foxyrollouts
    Awesome video, thanks for walking us through the circuit. Great job with going over and re-doing the wiring. I could view for another hour, to watch you doing that.

    I love it, Ohmite, Skokie, made in USA. Ohmite closed the Skokie (a Chicago suburb) factory in 1998, moved factory to Mexico, moved offices a few times over the years but still in the area.
  • Thank you. Reminds me of the repairs I did on laboratory equipment.
  • @TheRadioShop
    Excellent restoration Paul. I really enjoyed the theory on the inner workings of this piece. Thanks for another great video.
