You probably just want a HV supply, about 250 VDC, and a fuse instead of a constant-current supply.
I think IN-28's are rated at 13mA, so you could arrange them in groups of 16 with a 1/4 amp fast-blo fuse to protect each group. If power consumption is a concern, you can get clever and step-up the voltage to 250VDC for a few hundred usec when you know tubes will be turning-on, and throttle-back to around 180V for sustaining. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
