How long can a electrolytic capacitor last un-used?
Do electrolytic capacitors have a shelf life? I’ve an opportunity to buy an mono amplifier with 20 year old capacitors that have under 700 hours total use. The amps sound perfect without any issues. VTL Siegfried MK 1.
Agreed. They still dry out and will need replacing. Does it need it now? Perhaps not, but it will in next couple of years. If she is quiet with no buzzing or humming that is good.
