DC 12V to 80V-380V High Voltage PSU

Works well for testing nixie tubes. As described. Not expensive.

Good unit. Using for NIXIE project. Tested. Bought two. Both work fine. Remember, the voltage at the output is high. Even though the current is low you can still get a bite! Use caution especially if you have a pacemaker! Things get really exciting then! LOL

Does what I want it to do.

Item worked perfect and as stated. Received quickly.

this will not run on 8 volts , runs fine on 12 , listing is misleading . forget even 8.2 ! It would be much more valuable to all obviously if it really ran even to 4.5-5 v —- data in listing is wrong . PIA

Works great. Produces the advertised voltages and is very stable. Only issue is if you plan to enclose this at all or maybe run it for extended periods of time, get a heatsink for the IRF740. It will get very hot!! Other than that, highly recommended!!

I don't know if the circuit on the other flavors of this board is better, but the "black" board version is garbage. I'm 0-2 on these things. I've built linear power supplies in the past. There is nothing special about them. But they're big, heavy, and inefficient, so I tried to take a short cut. It turned out to be a waste of time. The first one, 12V input, 11V output. Adjustment did nothing. Exchanged for a 2nd. Exact same thing - 12V in, 11V out, no adjustment. And oh, to the person who designed this board, would it have killed you to add a 2nd mounting hole?

I used this to power a single 12AX7 in a bass preamp. Works like a charm!!

Handy for powering various things

used this on a Christmas decoration that needed 183 v. Worked .
