Well i finally got the tube i posted about to work using a MG Psu, works like a charm! (i had my camera sideways DOH :yabbmad: )

I just disconnected and reconnected the power to the psu and it now ignites an lases fine!

Sorry to bring back this thread, i got a powersupply hooked to it, and it ignites and lases, but its flashes, and the psu buzzes/clicks, am i just not feeding enough to the psu?

is there an easy way to drop the brick voltage?

I have a gas laser PSU, its a melles griot 05-lpm-830-065, and it takes 12vdc at .7 to 1.2 amps. All i have are 2 6volt duracell blocks, and some 18.5v laptop bricks at 4.9 and 2.7 amps. Whats the best way to supply the laser psu with the 12v at a steady ~1 amp, using what i have?

My dc power supply is fine. So I am thinking either the tube or the white thing attached to it is the culprit. Edit My DC power supply clicks when i plug it in, and it dims the lights in the room when it clicks. BUT i fiddled ever so slightly with the pot on the driver, and i got an ignition...

I cant seem to get it to ignite, Though i may have a Bad power brick. If the brick isnt bad, then is the tube or the voltage multiplier more likely to be the culprit?

It must be inside then.

@Mojo What would the ballast resistor wire look like? All the wires that are in the picture are the only wires on the unit, that I can get to without breaking open that white tube. And how would I short the tube? Just get a piece of wire and touch the ends of the red an black wires while...

well i touched it just a little, seemed to be either all the way on, or all the way off. but ill definately be careful

Also, as a PSU, would a computer PSU 5v, 12v, and then series a 5 and 12v rail for 17v work?

@things Alright ill try that Also, Will moving the potentiometer be any help when putting current through it?

Cant open the White thing, and its not AC i can tell that much. As i said it supposedly takes 18v, but past that i know nothing, would just an 18v bench supply work?

A few days ago i got a Spectra-Physics 088 from a HAM enthusiast on where i live, he claims it works, according to the person he bought it from many years ago. according to what ive searched, its a HeNe but please correct me if i am wrong. It and seems to have some sort of either power supply or...
