WebJan 9, 2024 · So if the unit is unplugged long enough, the only remaining energy sources with any storage duration will be capacitors. Any voltages above about 50 V are considered to be potentially dangerous. So if your stereo system is below about 50 W per channel (about ± 30 V rails), you are probably relatively safe, regardless. – jonk Jan 8, 2024 at … WebIEEE Xplore
