That sounds just like what I see on my NES.  I'd be willing to bet that we have very similar amp circuits.

All amp circuits I have tried so far have this same issue with the lines. Even the new ic amp
with the NJM2267 chip has this just to a lesser extent. It is most noticeable on light blue colored backrounds like the alternate level 2 in Dracula X. I wish there was a way to filter out this mess. Does anyone know how the portables process RGB to the LCD screen as that may be the best method.

I just built the amp the other day.  I haven't tried it with my NES, but the TG16 looks great and I'm not seeing the jailbars.  They may still be there but they must be greatly subdued.  I need to find some smaller capacitors, and then I am going to build one to stick inside the NES.

Build an RGB amp inside NES? I assume the Playchoice board?

I had to replace the NES's PPU with one off of a Nintendo Vs. Duck Hunt board (although you can also use the PPU off of a Playchoice board.  Then I built the amp and wired it up.

Ok so I am looking to build a new RGB amp, looking at the IC based amp you built jibba, it looks like this is one of the easiest RGB amps to build:

Any additional feedback? Did you build the amp exact to spec for the caps, etc or have to change anything up for the Turbo? And how did the NES RGB work out?

What do you guys think about this one. Please tell me it's kosher I just geared up to make a bunch of them (not a biggy the 47uf caps will come in handy for SNES/NES/N64 carts when they need to be recapped down the line):

That is simple but not the best option.

the ths7314 amps are one of the setups that is simple and has good feedback good. I personally have done the NJM amps.

- Who are you replying to?
- Do IC amps introduce lag?
