It is good.
The Miller Neutralizing caps, and the front end's g2 dropping R are the only things I can't fill in any more details about. Figure about 5" of the coax I'm familiar with for each of the caps, and adjust the g2 R until it gives the specified voltage for the front end.

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+.
cheers,
Douglas
