Looks a bit small? Anyway, I like this cause it has the capacitor codes on the circuitboard.

No probs I think from memory c323 is facing the wrong way though. I might put together a binder of printouts for stuff like this, I tend to use my phone, and it can be a bit small

I cannot remember if C323 is but you'll always use the polarity markings on the PCB anyhow. Yeah if you are doing these often a binder may be a good idea. I got the wife to print out and laminate one off the sheets at her work. I'll now get the same done with your combined layout

Good work mate this would have been helpful last week, though i have my other Duo to I know this is an old post but I was about to say the exact same thing, word-for-word! I did another Duo last week. It still needs a replacement volume potentiometer but at least it wasn't as troublesome as the Turbo Duo I did in 2018. Both times I made the mistake of removing all capacitors and starting with the most-numerous SMTs before the next most numerous and working all the way back to THT parts. While that works fine if you are using THT parts in place of SMT, it doesn't when you use SMT capacitors. C631 blocks you from getting your iron in to solder C653, for example. Yeah, that's my fault and I really should have paid more attention since I made the same mistake in the past, but maybe a couple markups to indicate a recommended order would help with those "gotchas." I felt so stupid when those memories came flooding back! Regarding the chart: Yes, C323 is incorrect but it is perpendicular to the real alignment which means it cannot directly lead to anyone putting it on backwards. It should have the same alignment as C613 and C614 above it. That said, I do not think we should trust users to follow the board alignment, not because it's incorrect (though I have seen some in the past), but because you may lose the silk screen markings when cleaning up the leaked capacitors that were there before. Fiberglass pen, desolder braid, corroded solder mask, etc all take their toll. One more note: Like many other men including my twin brother, I am color-blind. Though it is still easier to locate caps with the added colors (thanks again!), it is harder than it needs to be to distinguish some of these colors. For me, the color-coding here causes confusion with the 4.7uF and 47uF. The 4.7uF caps looks gray on the legend but white on the map. The only ones on the map that looked something like 4.7uF on the legend were the ones that are actually 47uF. Speaking of those 47uF caps, there is a tiny issue with the original map that we could potentially fix while we are at it: the size of C135 and C149 should probably be the same as C615 (all 16v) but they are shown closer to the size of C612 (6v).
