Hi Patrick:
Thank you for re-drawing the schematics. I have the original paper in my hands, and can say that:
1. C6 is 330pf
2. Question mark ("?") and lines near the driver transformer can be deleted. This was a white-out correction that Peter did.
3. R18 is 2.2k
4. Duno what the value of R17 is, probably original at 0.1 ohm as R16 or R35 in the original DX100B schematic.
5. Pin 9 of the 12BY7 driver may remain grounded as seen in the original DX100-B schematic:
