Re: NES no audio!!!
The chip is getting 5 volts, It would appear as if the inverter functions as a primary amp, which then goes to the single transistor amp shown in the schematic. I believe the by shorting C20 I am bypassing the inverter/amp and the secondary is just barely putting out something noticeable.

Re: NES no audio!!!
I started tracing back from FC1, I have audio at where it comes off the logic chip(74HCU04) but its dim, like volume maxed out and i can barely hear it dim, but its there. When I short C20(220p) this extremely quiet audio comes out the RCA jack. Keep in mind I want to keep this thing 100% original. ...

Re: NES no audio!!!
I have audio after the resistors its just quieter(duh).
NO AUDIO WHERE IT GOES INTO THE RF BOX, get a pop when I hook it up to the pin but no sound.
What happens between the resistors in Ben's mod and the RF box?

Re: NES no audio!!!
Alright, going off of Ben's faux stereo mod picture, I HAVE audio(rigged some jumper wires to my AV cable) at the points where he is pulling it as well at pin 1 and 2 of the CPU.

Re: NES no audio!!!
Tried RF and AV, dont have a scope(that works) or I would start poking. Found out that audio is pin 1 and 2 on the CPU. How hot is it from the pin?

NES no audio!!!
I took it apart to clean and it worked fine with the top shield and top half off. Then I put it back together the rest of the way and it wont make any noise. Video is perfect, 72 pin connector is a fairly recent Taiwanese replacement, the connector looks and acts good. I have it stripped down to the...

The only way to have mass amounts of tire smoking, wheelie popping power with 30+ mpg is to buy a sandrail and do a street legal conversion on it. You can get one for pretty cheap with everybody selling their toys for cheap and a custom canvas enclosure+lights shouldn't run more than a grand. A sand...
