recently inherited a non functional OB8 - good news is that it powers up and the lights change when different presets are selected however there is no audio output.
upon inspection it appears someone has replaced the battery (logical)
but also added a mysterious mod that comes a removed rectifier (i believe) and connects to another point on the circuit board as can be seen in the photograph.
does anyone know what this mod might have been for and how one might proceed in repairing?
