Hi All
I found a Coherent CR-18U power supply which from the front panel looks like a 0-100VDC 0-70A linear power supply.
It is a unit from 1979 and has a large 3 phase stepdown transformer to 120VAC and the regulation is handled by a massive array of water cooled transistors.
I think this is more for historic purposes and show'n'tell, than ever to get it running again, its not in a good shape.

Does anyone know where I can find data for the rest of the laser system? CR-18U did not turn up much on google. Neither does RCA 67339 transistors that there is many of in this unit.
