I created this Spice Script of the 6N16B Tube to show that the Tube Specification Guidebook still has some use and to help design an amplifier using this tube. I had difficulty finding 6N16B specifications that were not in Russian. The tube works great, even though I get a log() warning, and my gain is off by 5; I have not used spice in a long time. 😎 😂 You may have noticed that I designed my 6N16B as a single tube instead of a dual tube. It was easier for me to do the math that way (OK, I am no math expert, but I get by with a bit of help from my friends); the separation of the sections might explain the gain being off by 5 since the lack of interactive characteristics might explain the decrease in gain. Anywho, it works! Intellectual Exercises are essential for resetting the mind; I am just rediscovering that fact. In my original script I used LOG() but in this script I replaced LOG() with LN() to clear up the E1 Warnings. It worked on Multisim 14.3, but not on Multisim 12.3, go figure.

2moI figured out why it worked in 14.3 instead of 12.3. Math, yes, Math. In 12.3, you have to do the conversion of LOG() to natural log LN() in the script, which is: LOG e (x) = ln(x) when e = 2.718281828459 (Constant) when x = (1+EXP(KP*(1/ML+V(2,3)/SQRT(KVB+V(1,3)*V(1,3) ))) You ask, "Why did I choose to go from an EE down to an EET?" There is not enough crack to make me want to do this every day. (LOL) I did this for you, which drives me towards repeated sessions with my pal Jack Daniels and his partner, Jimmy Beam. BTW, I drink alone.
