I've had one of Grahame's clocks in my office at work for over two years using a Toshiba 5DEP31 CRT. It turns on every weekday morning when I walk in the door. I haven't noticed any phosphor burn. I did try a used 5DEP1 CRT that had some obvious burned areas. I keep that tube as a back-up. I also tried a 5EQP7 but found it had to be viewed in a dimly lit room. The long-duration phosphor looked nice though. Mike Mitchell -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
