My Turboduo has recently been giving me some trouble. I had it recapped and region modded last year by Keithcourage here, and it's been great. Gomola Speed and multiplayer bomberman are like crack to me haha. The sound has been a little "buzzy" (I cant remember when it started), but recently it has gotten really bad, so I only play on mute. Does this sound like an easy/relatively cheap sort of fix? I know the caps going bad affect the sound, but they're relatively new, so I was wondering if something else could be causing it? I've done some mod/repair work on gameboys/segas/snes, but I'm pretty wary of opening my duo. Since it's expensive, and I'm unfamiliar with it/how its modded, I'm unsure about what to do...
Also, I've heard Turboduos aren't the most reliable iteration of the system, so would you all recommend selling it and getting something else? IDK what all the versions of the systems are going for now. I play it pretty often, and have several CD games as well.
