Hello,

I recently noticed my 303 over heating. So decided to take a look inside, I noticed that the bias voltage on the right board was set at a whopping 0.320V while the left board was set to 8mV (correct). When I tried to adjust the bias voltage it would only go as low as 0.23V, way off what it should be set to. 

Does anyone have any suggestions as to what is going on or where to start looking?

thanks,

Ollie
