I have just started recapping the board and noticed that the capacitors CG13 and CG14, and CG14 and CG16 were switched on the board when compared to the schematic and parts list. Strangely enough is that the marking (circle around the capacitor) on the board fits the size of the capacitors when swapped.
Is it simply a misprint on the PCB and should I swap the capacitors (ignoring the fact that the original capacitors were swapped around, perhaps by mistake?)?
Perhaps the attachments will make it clearer what I am trying to describe... 😛

Agreed. Looks like the layout person screwed up. Oops. Later the mistake was noticed.
So equip like they were before.

Thanks! Just an other question... I forgot to cross check the values on the parts list with the schematics. Some of the values are different and I was wondering if I can just follow the schematics or can there also be mistakes in them?
@ sgrossklass The bizarre thing is that the caps were originally in the wrong positions (swapped).
Well, you could point those out here and see what the hive mind 😉 has got to say on them. If memory serves the service docs of this model are not free from mistakes.
So was that wrong wrong or right wrong? 😉
Our interpretation so far has been that you found the 1000µ where the schematic says it should be, but in the smaller spot for a 220µ on the board, and vice versa. Isn't that correct?
Ah.
The 1000µ/6.3 is actually smaller than the 220µ/25, isn't it? Then both the schematic and board layout would actually agree after all.
The schematic is definitely correct in any case. (The 220µ/25V needs to go in the power supply RC filter and the 1000µ/6.3V goes in series with 68 ohm resistor RG11 in the feedback's ground leg. If you can fit a 10 V, do that. Switching them around would sooner or later end in tears, as the poor 6.3 V cap is not at all rated for 15.5 V.)
