The Beitman's diagram has in series a 0.0047uF cap with that trimmer. A note says "may be used in some models". If your set has it, maybe it's bad?
Beitman's has 145V for the screen grid. It says B+ is 270V, so yours is close enough I'd think. Boosted B+ is 520V, terminal 8 of the flyback transformer (don't know it that is marked, though).

No .0047uF cap in this one.I think I'm a little low on horizontal coming out of the oscillator so I'll look there. The plate voltage on the 2nd triode is a little low at 142 vs 145 on the Sams not really alarming though.
