There is a separate channel for the sig gen, and other small changes.

Re: [neonixie-l] recommendation for anode resistor for 2x2 multiplexed IN-14s @166-170v?
Hello David, where have you found the factor 1.4 and what is your factor for 3x, 4x, 5x muxing? Dieter For 2x multiplexing, use about 1.4 times the recommended cathode current for continuous use. -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Dieter For 2x multiplexing, use about 1.4 times the recommended cathode current for continuous use. It's an educated guess. I used 3x current for 6 way multiplexing in the clocks I made, so 1.4x seems reasonable for 2 way. It takes experimentation to find the best value, and there is a tradeoff of tube life vs brightness. -- David Forbes, Tucson AZ http://www.cathodecorner.com/ -- You received this message because you are subscribed to the Google Groups neonixie-l group.
