Nanao MS9 cap listing and location


Conan The Librarian,

So I just finished recapping my Nanao MS9 chassis. This is the chassis with the PCB-MAIN 0500675C2. It is the one with the 15khz and 24khz jumper on it. I have removed every cap myself and note them down. This came from a working chassis, so I know all the caps are correct. The listings online don't have every cap listed because they all seem to not list the remote board cap and which cap is the bi-polar one.

Anyone able to put that in the wiki over on AO? This list needs to be immortalized.

Hi guys. Exhuming this thread for some advice :-)

I've got a Sega New Astro City with Nanao MS9 monitor, and monitor control board (located near joystick panel) 05A00675C1 (see photo). All works fine except for occasional brightness shifting between dark and normal brightness. Something on the little control board, I think, as it flickers when I tap it, and resolves when you thump the joystick panel, but I can't find any obvious dry solder joints. I removed then sprayed the board and components thoroughly with contact cleaner and it has improved, but still occasionally happens. I'm guessing replacing the brightness potentiometer might help? Is there anyone you can send these boards to for repair nowadays, or buy a replacement board? Where can you buy the components from?

This problem has been bugging me for a few years, and having recently got back into JAMMA games with some multiboards for Taito F3, CPS3 and CPS2 etc, I want to try to fix it properly now :-)

Many thanks for any advice, guys!
