So I cracked open a Duo-R last night to fix it.
When I got the shell open I immediately noticed this Duo-R has a Duo-RX motherboard. I then checked for the gear and yup, it has the Duo-RX gear as well.
Did any of the Duo-RX boards end up in Duo-R shells from the factory or is this most likely that someone swapped shells possibly for aesthetic purposes?
Obviously the boards look exactly the same but there are less caps and no fuse on a RX motherboard compared to a Duo-R. Some of the caps are of different values as well. The trim pots for the CD-Rom are larger and have plastic on them and stand up from the motherboard. The Duo-R has the regular small metal trim pots.
Let me know what you all think...
