In Reply to: Thanks guys! One more question, can I burn the woofer out? posted by vital ital on May 6, 2007 at 23:27:00:
Yes, if the cap or DC servo loop situation deteriorates, you could face a blown woofer or a blown amplifier, maybe both, depending on the amount of DC that leaks and how it happens. If the DC servo loop fails suddenly, it could generate a HUGE transient on the CDPs output.I have not seen bias adjustment, like a trimpot, on a CD player. Usually the designer blocks DC with a electrolytic cap or a DC servo (an op-amp that is supposed to cancel DC on the output).
Lytics caps are known to fail frequently in today's cramped. hot electronics; do a search on motherboard caps, all kinds of horror stories.
In the past, before the personal computer, lytic caps were supposed to last ten years. Currently, probably because of legal concerns, most lytic caps are guaranteed for 2,000 hours, less than 3 years of light usage or less than 100 days if your CDP stays on during stand-by!!!If your CD player is inexpensive or old, your best bet is to replace it right away, it will cost less than having it repaired. Also newer CDPs usually (not always) sound better than stuff made a few years ago.
Good luck
