LaserUser.com Forum (formerly RDWorksLab)

The young man [same age as me] who has bought my old 1300x900 laser was in today and I talked him into changing the tube on my old machine [still about 100w at the tube but 4.5 years old] now before he takes it- it is a lifetime support situation in any case so it is better to do it now... and I offered to pay for half of the tube cost.
So I am tube shopping, I have a EFR now and will look for a premium tube.

Just in case you still havn't bought the new tube, I'm acting as a guinea pig getting viewtopic.php?f=123&t=5300 , LOL, as there are no reviews on the internet so far...
