OK, I got my single tube counter working, sort of. It scrolls through 0-9 perfectly, but when five is on, six lights up to, and vice versa. I assume this is an overvoltage issue, any ideas how, or where in the circuit to best reduce the voltage? I'm using the tayloredge SMPS, an I have an 25k resistor on the Anode.
Thank you all
