This lets you mix a SID or Game Boy audio into the A220’s output. Wire to the right wiper pin of an

: Locate the four discrete rectifier diodes (or single-bridge package) near the power entrance on the PCB. : Locate the four discrete rectifier diodes (or

CODEC (A220) Analog Out --> 470uF (High-pass filter) --> 0.1uF (Low-pass filter) --> Volume Pot --> JRC4558 Input

: Insulate each solder joint individually to prevent shorts when the connector housing is closed.

Budget audio systems often skimp on power filtration, leading to a noticeable 50Hz/60Hz mains hum when no music is playing, especially as factory capacitors age and dry out.
