I'd run the nixies and probably the trigger tubes from a lower voltage. If you're using a doubler-style supply, this is easy - connect the lower voltage stuff at the 250V node, and the dekatrons at the 500V node. This will be much more efficient, and make using a single (two output) supply more feasible. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
