The 2001 schematic is attached. As for adding a vertical blanking pulse to the
first grid of the CRT, I would add a 22K 1/2 watt resistor in series between the yellow wire and the capacitor because I don't know if these old CRTs can withstand that 60 to 80 volt vertical pulse and not develop an G-K short.
Another way would be to send the pulse from the yellow wire through the resistor and the cap to the second grid. You might need to add a second 22K resistor in series with the B+ source that is connected directly to this grid.
Best luck with this set!
