Yeah. I'll have to think about that and play around with the numbers for these tubes again. I don't know what is going on with the internal structures of the 6SN7/6080 style tubes, but I think the...

Sounds good to me, but let's check. For your setup, what is the primary coil geometry and operating frequency you've designed for? From that we can compute the inductive reactance, and then the load...

Dollard Letters, 6SN7/6080/etc exciters

Here's a dropbox folder of letters (https://www.dropbox.com/sh/944xwdf37gjsxqc/AADkBXMkPX1qaX6whzMe0rsQa?dl=0) from Eric.

The more recent ones have 6SN7/6080/etc tube exciter information.

orgonaut314,

With your setup, you measure 4V dc at grid which gives Ip=4/560=7.14mA. I'm pretty sure that gets you a voltage gain of roughly mu=23V/V with about 6k of plate resistance. The...
