The troubling thing about the caps is that there's no polarity marking on them. To me that says, irrespective of the PCB markings, that they must be nonpolar, which would account for their size. Here's what a 50V 4.7uF nonpolar Elna looks like--note the absence of polarity markings--and that it's marked with the CE(BP) notation--you might want to see what CE(BP) means to Elna. (To the best pf my determination, CE=cerafine series and BP=bipolar. These were bipolar caps treasured for their use in audio crossovers. They're no longer made, but Elna has an equivalent bipolar audio series, as do other manufacturers).
Those capacitor markings aren't put there for decoration!
