According to the RCA Field Service guide, the -7 had the CYP22, the -9, -10, had the CYP22A, and the -11 listed the CYP22A, FBP22, or FJP22. As far as the NE2 lamps, there are 2 of them in series. Terminal #1 of the brightness control is connected to a 470K resistor and a .01 (to chassis ground). On the other side of that 470K resistor you will find 2 of the NE2 lamps in series to ground. Another way is to go to pin 2 (grid) of 6CG7 (V707-B blanker tube) which is directly connected to the NE2.
