i checked with them and they only repair at flat rate prices.  That would maybe be ok with a dead board but one with a minor sound issue for $150 repair is not worth it in my opinion.  Sent one namco board to SOS repair yesterday at the recommendation on Namco usa.

Anyone know of anywhere or anyone to sends boards for repair?  I have a dead rampart and a video issue on a steel gunner i would like to get fixed.
