PC Engine Duo RX Capacitor List

There are a lot of capacitors on a PCE Duo RX. The system used mostly Rubycon caps, with Nichicon in the CD section and a few Chemi-con for the HuC6260. All but two of the Rubycons were CE W ¹⁾ with two YK series. All the caps used in the Duo RX are general purpose radial through-hole electrolytic devices.

There's some debate about whether this was a series or a description. In any case they're a general purpose capacitor.
