I just missed out on one, on ebay :'(

GooeyGus said:diachi, this tube should do close to 200mW (at 10 or 11A) once you get it wired up for current control. Are you using light mode right now? Also, reflecting it off of a CD should show all 6 of your lines. Any idea on how many hours are on it?
If you need help with anything feel free to ask... I think between Dave and myself we could stock up a small university with these things ;D
randomlugia said:Anyone know if they work?
Unsure what to call this thing

GooeyGus said:On some tubes, all the lines wont show until the power is cranked up a bit. I have one line (a 7th line) that shows up at around 7 or 8A and then fades away as the power is turned up to 10A. I would attach some leads to your remote terminal so you can monitor the tube current with a DMM. I cant recall which pins exactly to use, but it is really good to know how high you have it turned. Sometimes light mode will only allow the tube to go up to its 'rated' power, and with a multiline the rated power can be reached at very low currents. For example, mine hits 40mW at like 6A. Another thing you may want to try in the future, is to apply very light pressure to the mirrors with an insulated stick (a piece of dowel or something) on the HR or OC end while the tube is lasing. If you see the power increase or you see more lines appear you will know that the mirrors are slightly out of alignment.
As far as how long you can run it at 10A, it depends on the cooling. The laser should shut itself off when it gets too hot. As with most electronics, heat is the killer here. If you have really really good cooling and your exhaust temps stay low you can run it at high current levels for a while. Many of the older Cyonics tubes were built like tanks. The cathodes were the same as the ones used in 5W models so the tubes can handle quite a bit, they just need the cooling. It just depends on what exact tube was put into your head
