Ah, ok. Thanks David I have built a µC controlled muxing tester... will put all about it on my homepage soon. I can switch from direct drive with rated current to muxed, with higher current and compare the glow. That makes it easy to find out the muxing current for a tube to get approx the

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
