I doubt IN-13s would suit this too well as they are quite a bit dimmer than IN-9s (hence the lower consumption and higher sensitivity)...
I suspect a couple of us on here may be interested in bare / populated PCBs if you are willing to sell them solo, as stockpiles of IN-9 tubes are quite common (at least around here!). My thoughts on powering a IN-9 field of tubes was going to center around a 115vac 50Hz isolating transformer and bridge rectifier (with very little smoothing for the tube supply) as that would give isolation and lots of current - the ripple also helping peg the tube at the right end... - Alex -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
