I'm a fan of direct drive myself. My advice is to ditch the 74141s and use a modern solution. Supertex makes a HV shift register, or you can use the old 74HC595 and either MPSA42 transistors or octal transistor arrays.
I've used the older MAX771 with success in quite a few clocks. These days you can buy ready-made DC-DC converter modules from several members here for about what it would cost you to build one yourself. You might just pick up one of those modules, slap it in your design and be done with it. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
