If the 5842 load to, let's say 5k opt, the gain would be step down and end up the linestage around 15x of gain.

That does sound like an appropriate application for a tube like the E180F. I have a couple dozen of them bought years ago. I sorted them by plate voltage and current at a particular bias and found at least half of them were very close to the data sheet.

I also used the D3a, but then got into high Gm triodes. The EC86 is generally cheap Mu = 68 @ 14mA/V Gm. It is well worth a try.
15X is too much gain (nt) - Triode_Kingdom 12:05:52 08/11/23 (0)
