I have an Atari 7800 (without the expansion slot) and would like to know the best place to pickup the audio for a stereo out mod thanks

Only NTSC TIA is stereo, the audio from the cart slot is mono.

What impedance are you trying to drive?

In which case you'll need a buffer like a transistor that can drive a low impedance. Search the 7800 section for suitable circuits/mods.
