I like to share a mallfunction in my laser tube There was no laser output Both epilog and coherent told me that the tube G50 is obsolete!! The laser machine is dead With no other choise left i disassembled the tube and was luky to find 2 bured capacitors - after replacment the machine refunctioned for some days and mallfunctioned again this time i did find any bured part I reassembeld the unit again and just of a sudden it functionagain for very short while Now it is not operate any more Any idea what can be done? Do you have a G50 tube for sell? Can any one handle this? Can I install another/similar laser tube? Thanks
