IN-23:
38k = K2, K4, K10 70k = K3, K6, K7, K9, K11, K13 160K = K1, K5, K8, K12 I used these values to get the correct current per segment at 170 V, which is listed as lowest segment current in the datasheet: https://rudatasheet.ru/tubes/in-23/ (you can translate it with google chrome) here is my 10-digit-IN-23 display i made: https://www.youtube.com/watch?v=ZfoV3-rsbNQ The currents for the B5971 are different: B-5971: 47k = K10, K13 22k = K8 39k = K1, K2, K3, K4, K5, K6, K7, K9, K11, K12 LB schrieb am Samstag, 25.
