AKG N12VR power supply - function BF423 New
« on: September 17, 2020, 02:13:43 PM »
Hello,

I'm intrigued by the use of the BF423 in the AKG N12VR power supply.
Would like to know the reason of using a BF423 in the high tension circuit. Why is the combination BF423/120V-zener better than simply using resistor/120V-zener? Reducing noise of the 120V zener?
