@Demented7th - I replaced the caps like-for-like with 47uF.

@desmondo - Ah yes, I vaguely remember replacing each pair of parallel-wired 47uF caps with a single 100uF cap. In the days that the WX-7 was made, it wasn’t possible to get 100uF in a small enough form factor.
Regarding your request for photos, I looked back, but don't have photos of the process. The caps in question are on the "DM circuit board" which is close to the mouthpiece of the WX-7.
