WebMar 21, 2024 · For some people, replacing the filter caps is the first order of business when they acquire a new piece of old gear. As components in the power supply, filter caps are subject to the most stress and the highest voltages. For these reasons, filter caps have a reputation as the most likely suspect when anything in the amplifier goes wrong. WebDec 10, 2024 · Once you have identified the resistor, hook it up to the capacitor using alligator leads and let it sit for the predetermined discharge time. When enough time has passed, remove the resistor and re-measure the voltage. At this point it should have achieved the safety threshold voltage. If not, replace the resistor and let it sit for a while …

WebTo make this circuit safe we need to provide a symmetric current path to discharge the capacitor when Vcc - GND is negative. This can be easily done by adding D4-D5-D6 and LED2 as in the schematic. When Vcc - GND is positive, current will flow only via D1-D2-D3 and LED1. When Vcc-GND is negative, current will flow only via D4-D5-D6 and LED2. WebThat being said, some types of capacitors (tantalum and some organic semiconductor types) do need charge/discharge current limiting.
