I have a Black and Red, originally with a 60W tube.
About a year ago I upgraded it to a 100W Reci tube and DY10 PS and installed a mA meter.
It's been running fine but it the mA meter started showing ~10mA at 65% power where that would register 25mA in the past.
The tube's still generating a purple beam and the PS test button lights up the test LED nice a bright.
At this point, I'm not sure if the problem is the Tube, the PS, the mA meter any or all of them and someone elsewhere suggested a bad PS supply can kill the tube.
Any suggestions before I start ordering replacement parts would be appreciated.
