My old power supply finally bit the dust. I don't think I would use any power supply continuously at more than 75% of its rated output, you're just asking for problems when it's made in China. I will see if I can repair it but will most likely buy another brand. It's hard to find things that are made the old way, heavy, metal and analog. It is doing the job wellOn the down side, two things I would like to see improved: first the fan is noisy -- I may rearrange my bench so as to help dampen the noise.
