Good points... The circuit is intended to be installed internal to a housed device, but ESD definitely an issue prior to and during installation. Adding belt and suspenders can't hurt. And I'm sure we all work at a bench with a grounded mat, wrist strap and good bench hygiene...

Before you fab it, you might want to put some protection between gate & source to prevent ESD damage since this is a separate PCB and wont have the benefit of surrounding circuity until after it's connected. A large resistor (10meg) across C1 will keep C1 discharged. It's not entirely obvious,

Think about what the tubes were used for, back then. They often replaced an analog meter. When using equipment with different scales, or multipliers, it was up to the user to select the appropriate range for the measurement, then read the meter or tube display and "do the math" himself, to

Yes, maybe there was never a need for such a tube, so they never made one or at least we haven't seen one yet. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this group and stop receiving emails from it, send an email to

Looking good to me in sim land... circuit meets my design objectives up to and beyond 12 VDC with loads above 3A. Caution: Watch out for heat with higher loads... Small pcb shown will not support the resulting dissipation with these high loads...

Thanks Jeff I am trying to adjust everything for optimum performance and reliability before my tubes arrive. I have not soldered in the 270K resistors for the colon neon bulbs so wondering if a different value would work better or if these would be fine at 180VDC instead of the 170VDC that was

A 2A power supply is definitely not needed. 0.008A (per Tube) x 130V x 6 (Tubes) = 6.24W 6.24W / 12V = 0.52A + power for the rest of the electronics, a 1A power supply fits best. I'm using this one (rated 12V 1.25A) https://www.pvelectronics.co.uk/index.php?main_page=product_info=10_id=161
