HeCd Laser

[djmatt]

My frist HeCd laser!!
Well long story short, I just got a HeCd laser for basicly nothing
Heres the specs.
Omnichrome Series 74
3074R-SL-A03
Date Manufactured June 2004
Serial number: K1268

I gave it a good cleaning,and tested the tube and it seems to be fine,but the color is orangish-blue in color, so I dont know if this is good or not.
But here are some pics. of it.

Oh anyone have a PSU for this head?

Oh my , looks like the tube is broken somewhere - it's not firing down the bore. NOT good! I just sold one of these lasers ( Manufactured in 1993 with 92 hours on it when I got it ). The discharge should CERTAINLY go down the bore and be BRIGHT orange, not around the side of the bore!



EDIT: Ooooooooh just realised - it's not going down the bore because you haven't got a PSU!

PSU for it is model 100B from omnichrome.

Yeah, Im just hiting it with a gas lamp tester, but it has more or a orangish color to it now, I guess my tester need new batts.

Yeah I would love to find a PSU for it!!

yeah I figured that after I actually read the post !

It should be really quite orange from the helium, once you get a PSU for it the cadmium in it will make it whiteish orange.

EDIT: Good luck finding a PSU Shipping may be expensive, they weigh a ton

[djmatt]

Yeah... I was just thinking about that.... But this head isnt light ethier.. but the PSU is going to weight a ton
Id just like to find one, Ive found a series 88 psu, but I belive it has to be a 74. or am I wrong?

Well I know have 2 more HeCd laser,this time with psus. But I have yet to get them lasing.. one will only light for a few sec, then go out, but when its lit, it makes a buzzing sound. The other one lights for longer but then it will flicker the go out..... any ideas?
