I have a slight suspicion that the power supply might be bad, after testing it on what could've been 2 fine tubes. I just find it hard to believe that my brand new power supply could be broken out of the box. I would like to be able to find out if it is bad for sure so I can get a replacement part sent if needed (Still in return period for the parts). Is there perhaps anything that might stop the laser from firing (like a safeguard or switch) when using the test button on the laser power supply?
