Hi, I’m new to gas discharge lasers and found a few old boards in my community college. I was granted permission to see what I can do with them, and I am hoping to get them in working order using the original drivers. However, I have never seen this driver board before, and I saw a post made by a member about a laser with the same driver, but it was a different laser. The laser in this driver is a LGR 7655A, which I cannot find any data on at all. How do I power this specific board? Is this one straight 120v input, or am I underestimating the circumstances?
Thanks, I’d love to get these running again.
Also, I replaced the bad components and measured values as needed, everything looks to be in perfect order.![465FB347-6CD6-47C0-A007-016BC136DA57.jpeg 465FB347-6CD6-47C0-A007-016BC136DA57.jpeg](https://laserpointerforums.com/data/attachments/51/51279-4f6b2619ce863625ba998cd35c271ba3.jpg?hash=T2smGc6GNi)
