HeNe Tube voltage Info? (pics)

Alright, my new interest in gas lasers, mainly helium neon's has led me to buy some things from heNebay, one complete inclosed system, one complete bare tube with powersupply that I have just bought, and the first bare tube I bought, which is what this thread is about:beer:

So does anyone have any ideas if the seller's 900-1200v rating is accurate? See pics below:




Im also wondering if maybee I can use the 1200-1600vdc powersupply that is coming in with my newest order?
I like this tube alot because it shows more plasma than some of the others I have seen.

:beer:

1200V should do it. You should be able to use the 1200V-1600V one you have coming. You may have to increase the resistance, but probably not.

Peace,

He'll need to rectify and filter it too, as he specified 1200-1600VAC not VDC.

Oops, typo, sorry about that guys. It is AC input, DC out, here are the specs from the power supply:
Power supply model: Melles Griot 05-LPM-959-04
Voltage in: 115vac or 230vac
Voltage out: 1200-1600vdc max

Thank you Daguin for the advice. Thats what I was hoping, so I dont have to go hunting for another power supply.

You will need a 75K to 125K ballast resistor abd 1100V or so to run your laser tube. Yes this 05-LPM-959-04 is the correct power source.

Excellent, Thank you:beer:
I ordered 2 75K ohm ballast resistors from merideth a few days ago, hopefully I will have it up and running soon

EDIT: 666th post! :eg::eg::eg:

I got this baby up and running today I bought a cool little power supply from meridith to run this tube, the supply runs off 7v-9.5vdc and outputs 1050 to 1450 VDC. I wired it up with a 75k ohm ballast resistor. Using 2 3.7v CR123's it ran smooth for a few min, then started flickering, so I wired up two 18650's and havent had the problem again yet, so I belive I was getting some input voltage sags.

Some neat pics:







Here is the link to the power supply if anyone wants one:Meredith Instruments : 7 to 9.5 VDC Miniature HeNe Power Supply [LPM-827-037] - $39.00 - The source for laser surplus
I plan to use it to make a small portable HeNe lamp that runs of two 18650's

SWEET!

Keep us up to speed with your development of the build

Peace,
