Hello friends, i have a MV1c with a homemade Supergun, i use a +5v/+12v PC ATX DC supply and works all fine.

But now i want to use only a +5v Dc without the +12v line.

I do it and MV1C works fine but NO SOUND, i up volume to max and nothing, 0.

I dont care about Stereo or mono signals, i want only sound can do work my supergun with 5v and have sound without modding MV1C board?.

Maybe re-wiring Jamma pin 11 to SCART ? At the moment i have Pin 10 wired.

Thanks!.

the 12v feeds the sound amp
to get sound, you either have to feed the board with 12v or get the audio before the amp (soldering in the mv1c)

This, if you do the stereo mod you bypass the amp so no need for the 12V feed.
