    Default WTB spectra physics 155 HeNe tube

    I was given a spectra physics 155 HeNe.
    looks like this


    It needs a HeNe tube like the bottom one in this picture


    Anyone have one I can purchase from them.

    Please note the top one is the wrong size and needs to be re gassed

    I have an SP-155Asl with a working tube in it I'll trade for your dead 155. Mine is from 1987, has a white paint job and is doing 0.7mW right after turning it on. I'll leave it run and clean the OC this evening and we'll see what it really has. Anyway, I'd rather have the gray head with a dead tube than a working one from the '80s. The tube is also different in the 155Asl, being coaxial instead of a side-arm.

    I'm only interested in the "look" of the old laser, and the one you showed looked very good. Could you post or send me a picture of the one you have? I'd be happy to trade this one (doing 1.1mW before the internal attenuator, 0.9mW and lower after it), but not if I'll be wanting to find a better looking gray one. I'll take a pic of it later today or this weekend.

    How long does your tube need to be? I'm surprised that one would be too long.

    Sorry for the delay but i have been swamped with homework ever since Christmas break ended.
    Any way I was able to get a working SP-155 laser from here http://www.repairfaq.org/sam/sale/ cheaper than I could get a replacement tube.
    I will however put the gray case along with the internal circuit board up for sale on eBay as soon as I can get a chance.

    I will let y'all know when I do.
