How do you choose a power supply when you buy just a gas laser head? Normally, I would guess you would look at the specs and find a PSU with the matching specs, but what if the seller doesn't have any info on it? And googling the model # doesn't help much? Is there any way to "measure" the voltage and current it pulls? Or am I just out of luck?

I'm not an expert on this, but usually you are fairly safe basing it on the length and color of the laser. Short ones (6") are lower voltage than a Long one (20"), Red's are generally lower power for the same length than a green or yellow.

So, if you have one, post a pic, the length of the tube and if it's a red or other. then based on that we should be able to give you a fairly good guess on the voltage and the current.

What about the start-up voltage? That varies a lot by model, and I don't see it listed on the specs of a psu a lot of times...
