What would I have to go about doing to add in my own opamp?
Adding your own opamp is really easy. If you look at the datasheet for the one that came on my FC Twins, its just an 8 pin, dual amp chip. You supply it power, and feed it left and right audio signals. The amplified signal then comes off of alternate pins. Very simple.

Before you do anything, double check your NES board to make sure the resistors and caps are the same values as mine were for the 4->2 audio mixing stage. The reason the opamp is there on my boards is that the signal from the SNES boards is just a little too low for line level. If yours doesnt have the opamp, then something else must be different.

Shmagoogin77: Thanks bud!

grahf: I took the caps off the NES board to use, but I can't tell what it says exactly for the resistors... its either 33k or 3.3k... I guess thats a huge difference...

Dear Friends,
Khaag got a huge problem with my Snes P...
Here it is:

I REALLY WANT THAT F**** HEADPHONE JACK OUT. But Khaag used a Twin Famicom and told me he didn't manage to put it in... He said that the Twin Famicom is quiet different for this part (Snes part).

Can someone HELP HIM about this thing please???


thanks!

Yes, just take the audio and hook it up according to this diagram, assuming he's using a Zenith/PSOne LCD screen. It's really easy.
