WTB: yellow HeNe

I would like to buy a yellow HeNe. I don't need a PSU as long as the tube will run off of the PSU I have for my red HeNe. The PSU is made by Uniphase and its model number is 314S-2300-6-4. The output current is 2300 VDC @ 6.0 MA.

Check Ebay every once in a while, you might find a good deal there.
Worst comes to worst you can buy a brand new HeNe tube and laser system from Meredith Instruments.

Lucky for me I found one on Ebay for a very nice price, the original buyer got it from Meredith, so I can vouch for them.
