Questions about tubes and gear that glows. FAQ

I am trying to repair my MC240 amp. I am now using a PHOTOFACT schematic of 1961. The problem is that I have already replaced the 4 electrolytic aluminum can capacitors and the 3 rectifiers in the PHOTOFACT schematic show a different polarity than the ones in the unit. I am inclined to continue the repair with the PHOTOFACT, and will have to switch around the rectifiers
as shown on the schematic. How trustworthy are the PHOTOFACTS?
Any suggestions are welcome.
