PC Engine DUO-R Maintenance & RGB Output Modification - Tested and Working ○ Electrolytic capacitors all replaced - Rubycon ZLH for the power supply, Rubycon MH7 for low-profile areas, and Nichicon audio-grade FG for the rest ○ Supercapacitor for save memory retention replaced with a high-capacity one ○ Additional bypass capacitors for image stabilization ○ AV output terminal replaced with an 8-pin, RGB output added ○ RGBs amplifier output improved (improves stability with XRGB mini, etc.) ○ Controller port replaced with one with larger metal supports ○ CD drive drive unit maintenance, pickup cleaning & adjustment ○ Turbo Pad maintenance ○ Genuine AC adapter (PAD-129) maintenance, including electrolytic capacitor replacement The items for sale are the following four: DUO-R main unit, maintenance & RGB modified Turbo Pad (PI-PD6) - maintained Genuine AC adapter (PAD-129) - maintained RGB cable (Please choose from JP-RGB21 specification or SCART specification) As a bonus, a genuine stereo AV cable is included. (It is currently working, but its condition cannot be thoroughly confirmed, so it is not guaranteed.) The rear switch allows you to switch the sync signal for RGB use between C-sync and composite video. When using a standard stereo AV cable, switch to the lower position (composite video). C-sync has been adjusted to work without issue with RetroTINK 5X Pro, CRGB mini, etc. Please select either JP-RGB21 specification or SCART specification for the RGB cable when you win the auction. Since many people prefer no termination resistors, they are not included by default. If you want termination resistors, please let me know. RGB output has been tested and confirmed to work with the following devices: WEGA KV-21DA1 AV multi-terminal (using a conversion cable) WEGA KV-14DA1 AV multi-terminal (using a conversion cable) RetroTINK 5x Pro ODV GBS-C XRGB mini
