[Part] C13, C14 [Size/#] 12mm case [Value/Notes] 
I seem to have skipped C8 on the schematic. These are the main PS decoupling caps. They should be big and at least 35V (technically they can be smaller in voltage, but if the rail splitter goes south, you'll be happy they are over spec'd). However, there are two considerations. One is that the case is only 12mm, so they can only be so big. The other is that they are right by a heatsink that is going to get hot, so 105 degree caps are a good idea. Panasonic makes a 1500uF/35V cap in the FM line that will fit this spot (though they also make one that won't, so check the datasheet.) Also, Nichicon part #647-UDW1V152MHD6 is the same.
