If you are connecting your Stereo Board outputs to a stereo
amplifier or to speakers with built-in amplifiers, a simple way to mix
in 'Old Apple' sounds is to connect a capacitor from the signal ("+" or
non-ground) Spkr lead to one of the Stereo Card outputs.
This connection mixes in combined (mono) IIgs sound, too. This is
why a pot is included in the circuit. It lets you adjust how much of the
Old Apple and mono GS sound to mix in so that, when sound is coming
through the Stereo Board, the Stereo Board sound will predominate.
The pic below shows a 5uF 15V non-polarized electrolytic cap
running from a pot across the Spkr leads to the center of the Right
Output socket. (You can use a couple regular 10uF caps connected back to
back.)
