@ Dekatron42 So looking at this info and please excuse me if I make a mistake (still learning schematics) Would the 1st stage be R4 and R5 in Dieter's circuit represented by the 1/4W 4.7M resistors? http://www.tube-tester.com/sites/nixie/different/spinner-EZ10B/ez10b-spin.htm
So I would need to make them 150K resistors like in your diagram on this link? http://www.seekic.com/forum/22_circuit_diagram/24850_500000_PPS_SCALER.html John On Oct 5, 12:58 pm, Dekatron42 <[email protected]> wrote: > I knew I had seen a circuit somewhere, and now I found it on the > Internet too - it was in my "Markus: Sourcebook of electronics > circuits, McGraw-Hill" which is a collection of schematics from > different magazines, and here is the > link:http://www.seekic.com/forum/22_circuit_diagram/24850_500000_PPS_SCALE... > there you can see what voltage and anode resistor that is used with > the EZ10A dekatron.
