CTC-4 sams photofact
 

I was comparing the RCA circuit diagram for ctc4 and CTC-4A (changes) and wanted to make sure I was reading this right , as an example C4b 500mmf in the vert centering circuit (C117C on rca diagram) , shows NEG - going to ground but on the sams photofact shows POS + to ground , if this is so there are a few other differences between the 2 prints. Can someone who has replaced C-1 -2 -3 - 4 - 6 caps one the ctc4A chassis tell me if they had rewiring problems and also what print they used?

vert centering
 

I was just using vert centering as a reference point(sams photofact) for the C4B 500mmf cap and looking for the correct wiring connections for C-1-2-3-4-6 caps?
