Hi folks, hoping someone can help me diagnose a problem.
I just installed a brand new power supply from cloudray. The power supply has a nice little screen with a digital milliamp meter, and I've also got an analogue meter on my machine. When I pulse the beam I get readings I would expect from both meters and my tube lights up with a strong purple glow, but I'm getting practically zero output. I put some tape at the end of the tube to rule out any optics alignment issues and there is only the faintest hint of burning on the tape. I checked that the min power on the controller is set high enough to get output and that didn't help. I tried running a file that has worked in the past and that also had no output.
This is the power supply I purchased to replace one that was shorting out:

I should note that this is a fairly old tube and I had been noticing some power reduction when I used it last, which was several months ago. Is it typical for a dead tube to still be lighting up purple? Is there something else I could be missing?
Thanks for the help!
