Mod Kit : RGB - Triple Bypass V2 Megadrive 2 / Genesis 2
 
Includes new replacement MD9 connector
 
Latest RGB and audio amp mod for the megadrive model 2 or genesis model 2 consoles. Bypasses original circuit and uses video and audio amp to improve video and audio quality.
 
V2 (3BPV2) is an RGB bypass board and audio amplifier board in one. This board implements two different mods in one, a high quality THS7374 video amplifier that cleans the signal and provides crisp clear pixels on your monitor (it also resolves the infamous "jailbars" issue mostly evident on Mega Drive 2 consoles), and the "Mega Amp 2" mod that cleans up the console's muffled audio (again, most notable on Mega Drive 2 consoles).
 
Compatible with this high quality screened scart
 
Compatible with the retrovision megadrive 2 / genesis 2 component cable
 
VA1 motherboard install instructions:
 
1. Remove these component around the BA10324AF chip on the top side of the motherboard, this isolates the audio signals and removes any audio related electrolytic caps which are no longer needed, as these will be on the 3BP board. Remove R21, R22, R24, Remove and bridge R72, R73, remove electrolytics CE10, CE32, CE4, CE2, CE5, CE8, CE1, CE31
 
2. Lift pins 21, 22, 23 on RGB ENCODER CHIP: MB3514
 
3. Set jumpers on 3BP Board: Model 2 VA1, set jumpers: 2,c,d-right,e

4. Trim pins around md9 connector, (optional: remove md9 and replace with new connector, this makes soldering the 3BP board easier) Tape the underside of the 3BP to prevent any shorts, and just to be on safe side) While you're at it trim the bottom shielding this will stop shorts!

5. Solder on 3bp board using fine point tip set to 400, ensure you're melting the solder points!
Check for 5v and gnd short with multimeter before continuing.
 
6. Solder rgb and audio points as pictured. The solder mask on the RGB via's need to be scraped away. Be careful.
