    Great review, thanks. I love these boards and have several now. They work great with a 24v 90VA transformer or higher.

    I really like the tool you use to make the bend/indentation on those resistors. Could you tell what model number that tool is? I see it's made by Medentra, but I can't find that specific plier.

    Hope you believe me when I say I appreciate the effort you put in making this video but it is made for others with same level of understanding as yourself, well I'm a novice who is looking for a video on how to connect a volt/amp meter to this DIY power supply, at 9:03 I looked at how your V/A meter was connected but you had too many objects on your desk, could not follow the actual wires that go to the V/A display, so basically I 'm not better off watching this to the end to learn something, I wish you showed how you wired the V/A display on its own without other distractions.

    Hi there,
    If your transformer could output 19v AC then you should have been able to get around 24V DC on the PSU output, you only got 14V DC.
    Did you figure out the problem?

      So there is tin wires red yellow and black and tick wires red and black. The tin wires red will be connected to the voltage regulator that supply the voltage for the fan on the positive side and tin black goes to negative. The yellow will be connected to the output positive and the tick wires goes connected in series with the load

    I bought two of these bt psu boards and its not very good.
    3A ? I couldn't get 3A out of mine.
    IiRC it wont get to 30V either.
    Apparently these counterfeit Hiland Boards seem to be an abomination of the original genuine Hiland boards which I built a many of these. (Fake 0-28V 2A.) The original Hiland regulated psu were apparently pretty good for the price but these no.
    Still they're an interesting build unfortunately they're not the original Hiland boards.
