Chief No, I tried it, never worked at all. The directions specify a 24 volt AC Only! That said, when I built it up, I tried the DC PS on it, nothing, all I had was an old 110 to 26 volt transformer I had picked up at a swap meet. So I decided I only had a few bucks and about an hour building the kit, why not try the 26 volt transformer. Works GREAT with the 26 Volt AC output. I mounted it in an old 3 1/4 inch floppy case that used to hold about 25 floppy's and added some banana plugs as well as a DC power out plug, and an AC power in plug pulled from an old computer PS, as well as a nice power LED, and I now have a very nice variable power supply on my bench. While I didn't keep track, I don't think I paid over 10 bucks for the total build, if you don't include my time building it all, and since it is a hobby there is never a charge for that. I finished it several months ago, and use it regularly when I need both voltage and current control in a test circuit. I have another that is not as variable that I just control the voltage out on.
