Title: PC Engine RGB Amp ( NJM2267 ) Sync Boost?
Post by: BackForwardPunch on February 24, 2014, 04:36:51 AM
Hey, I was taking a look at the possible RGB amps for teh PC Engine and this amp, shown here for 64 (http://www.gamesx.com/wiki/doku.php?id=av:n64rgb-amp (http://www.gamesx.com/wiki/doku.php?id=av:n64rgb-amp)) shows up as the suggested one to use.  The original PC Engine amp had a Sync Amp also.  Is there anyway to boost the sync using this amp?  I tested it out unamped, and the colors are very dark, of course, but the raw sync is pretty finnicky.  I plan to build the amp to boost the brightness, but what should I be using for the Sync signal?

Thanks in advance.

Try this amp for the sync signal :)

I would much rather recommend using the THS7314 amp and having composite video for sync.

Hey, thanks very much for the schematic.

@AppoloBoy I guess you are talking about http://nfggames.com/forum2/index.php?topic=4822.0 (http://nfggames.com/forum2/index.php?topic=4822.0) this thread?
Is there going to be a huge difference in output?
