What's up, guys? I have some sound issues with my recently acquired NES (toaster). Audio is OK, except for channel 3 (triangular wave), which seems to be absent. As a result the audio sounds shallow, as channel 3 is usually used to play bass lines. The other channels, as far as I can hear, are OK, though. Have you guys ever seen some seen something like this? What do you guys think might be causing this? Maybe a damaged cap? I have never opened the console. I have checked the AV cable. It is OK. Tested RF out: same thing happens.
