I have been reading that the CAD 3000(or the Apex 480) have an issue with slightly low voltage to the capsule resulting in poor response in Figure-8. As recommended, I would like to change the zener in the mic's power supply. The problem is I can not read the value/model of the zener and do not want to remove it just to see the value. I would prefer to know all of the parts I need before ordering. Does anyone have any experience changing out this zener? It is D1 on the power supply board. Any help would be much appreciated.
