Do you want me to send Heyboer the S-230-Q for cloning? or did you have another output in mind? I'd guess at a little bit lower price for the smaller 20W v. the 40W S-265-Q which also had the E-Linear mods done to it.

The dropping R will also depend on the B+, which I'd suggest making right on 300, maybe plus a bit, but no lower. If you cathode bias, add 60V to the B+.

I will hopefully have a serious distraction for my amp building in the future, hence the offer I made in the 'Vault' post below. Make the arrangements with Heyboer and the original will be delivered for unwinding. Don't worry, it is only a single that I acquired just for that purpose, and moving the schedule up so somebody else can benefit looks like a reasonable thing to do.

I am still contemplating a cathode driven PP 211 running near 1kV and using a 3k:500 as a PP:PP IT. Maybe drive with 6L6GC in E-Linear. Nice thing is the cathode is a fairly flat load to drive so a lot of NFB/damping factor won't be needed. Maybe after the 813 project...:)
