Looking For Help on a Coherent Deos tube

[Gary Hair]

I am looking for a Coherent Deos Gem Laser, 30 watt tube. My Explorer is running fantastic, but it's coming up on 7 years old and I'm pretty sure it's living on borrowed time. I have a few large accounts that I can't afford to be out of service while waiting for the tube to get refurbed, and don't really want to pay expedite fees if I don't have to, so I'm trying to be proactive and find a tube that I can ship to have rebuilt if/when mine starts showing signs of dying. I'm sure Rodney has a few laying around, but the shipping from him to me would kill any savings by not paying expedite fees.

Thanks!
Gary
