310A (328A) triode curves

I saw that in there.. Is there a way to draw the curves from the text representation of them? I like a graphical view of the curves to help me with them.

Yes, to reproduce the curve you use a test circuit and DC sweep analysis you need to set the display scale after to suit, refer to the original for scale setting.

Eg dc V1 1 2000 1 V2 list 0 20 40 60 80 100 120 140 160 180 200 220 240
This one sweep anode from 1 to 2Kv and grid 0 to -240.

Awesome! LTSpice is really quite amazing 🙂 Thanks.
 
Does anyone use the 310A in triode mode? I really like the look of this tube, and it appears to be very well constructed in general.

I came up with a design using a 310A in triode mode with CCS plate load feeding a 6AH4 with CCS plate load, and it would provide the necessary swing for my amp.. I have a large supply of 310A tubes, so part of me would like to make use of them.

It seems like most people use this tube in pentode mode though.
