The only difference I see from original is the yellow/blue stripe and yellow/green stripe wires (pin 13 and 5 hooked together) move from the original position on the 2.7k ohm resistor (R71) to the 1.8k ohm (R70), they are now connected to the extreme end by the video output board where the peaking coil is. The yellow/red remains connected to R69 as per the schematic. see pics. I'm not an expert on this mod so if anyone else knows something, please chime in. I'm just going by what was done to my set, the picture tube was changed by the RCA service company so I assume it is correct. The tube was installed 4/15/68 and is still going strong.
 edit: I'm not sure my set is right, so I took down the pictures.
