Found issue with one cap. It's in the wave shape section of the Vertical Output section. The cap in there I tested and it's was at the low end of tolerance (81uf of 100uf), so I decided the new cap would go in. Upon looking up the schematic, I noticed that the cap is in backwards. The schematic shows the positive side connected to the diode and the negative to the resistor. It occupies the same connect points as R292 and one leg of R293. I've attached a pic of how it was and the part of the schematic. In the pic you can see the negative side of the cap connected to the diode.
Am I interpreting the correctly? Even in the SM, the crappy pic of the underside it appears that the positive side is down on the diode side. I traced the path exactly as the schematic shows. The green/red lead connects to the diode, the other end of the diode connects to both the positive side of the capacitor and 470ohm resistor. The other ends of the capacitor and resistor join up with the lead of the 68ohm resistor and the other end of that resistor meets up with an orange wire that goes to pin 6 of J201. So if the last cap was put in backwards, why didn't it fail or cause issues with the circuit?
