Even if the capacitor was properly made they still only have a finite lifespan typically 10000 100000 hours. Sometimes in an effect called microphony parts will pick up sounds or vibrations and inject them into your audio.

When cooking up good sound audiophile grade caps should be on the list of ingredients.

Replacing capacitors amplifier. When a charge is placed on the capacitor then removed an echo of the charge can reappear on the plates as if by magic. Not just the power supply electrolytics or caps that test bad but all caps. How to choose replacement capacitors when repairing and restoring high quality electronic and stereo equipment in any type of electronic appliance a microwave oven a refrigerator a cd player an amplifier a computer there is no single component which has a more profound and direct influence on the.

Capacitor replacement tutorial you may have heard about infamous capacitor plague problem where crappily manufactured capacitors died prematurely on peoples motherboards.

Capacitors and other parts are often glued into place in audio circuits. Replacing capacitors with low leakage units is always a good idea. Finally capacitors exhibit a curious behavior called dielectric absorption or da the capacitor acts as though it has a memory.

Lets say we want our applied voltage to be 650v then rb1 and rb2 325k ohms. One common rule of thumb for the balancing current is 10x the leakage current thus for two 100uf350v capacitors connected in series to form a 50uf capacitor maximum leakage of 12 sqrt 100350 94ua times 10 is about 1 ma. If they could move then they could cause noise.
