WebIf the possibility of high DC voltage being that close to head bothers or worries you, then the coupling capacitors are a good workaround. Bear in mind, if a capacitor is going to sing, it is going to do so in this position, due to the several hundred-volt swings. (Singing capacitors are like mini electrostatic loudspeakers. WebOct 5, 2024 · Just unlucky combination of parts and parameters and capacitors start singing. Well with a linear supply, what could possibly happen that leads to this condition? All that comes to mind is something with the diodes, the transformer windings shrinking (inductance change), and perhaps down stream decoupling capacitors having lower …
