I'm just wondering if DHTs could be used in such a cascode design. 6N30 has a Rp of about 1k and mu of about 15. I don't know any DHTs that are similar, so I don't know what to prioritise - the mu or the Rp?
there are some bigger output DHTs like 2a3, 71a etc but that would be very wasteful.
I'm wondering if something could be done with the 31. cheap and easy to heat - Rp of about 3.6k and mu of about 3.8. We've strayed quite a way from the 6N30, but the 31 sure sounds nice to my ears. Any use?
