I'm considering purchasing a used LASOS LGK 7872 ML02 Argon Laser, but it doesn't come with the power supply. I see for sale a used Uniphase Model 2113 power supply. http://www.midwest-laser.com/2110ps.pdf Would they likely work together? I apologize for my noobiness. Also, what does it mean that the power supply operates on a 200-240 Vac power source and what can I do about it? Do you know of a better power supply for a reasonable price? Thanks in advance for your prompt help!
