WTB spectra physics 155 HeNe tube

[Lazerman121]

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

Hey!
Yeah Id say that tube has seen better days..
Ive got the same SP 155, and it was the hardest thing to get to lase... But after all the work it lases with all its .95mw glory
I might have a tube that will fit that, that came out of a JDSU, Ill look tom for ya.

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.

Can I get a picture please.
also please note mi case for the tube is a little weathered from general use its not is as good condition as the one in the picture.

that tube is too long what about the white one you wanted to trade.

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.

[Lazerman121]

It needs to be like the bottom one in the picture the one you linked me is like the top one. If you PM me with your email I will be glad to send you some pictures.

I have a tube that runs fine but is onlt about 0.30 mW @ 6 mA. Easy start, god color but low power. $25 plus shipping $40 total. Phil 142laser

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.
