I posted this over on AVS as well, but I figure there's a better chance that someone here will have done this already... :)
------------------------------------------
A couple of weeks ago, I picked up a used Dayton SA1000. It was extremely quiet (no humming, buzzing or any other sounds) when I got it, and for the first week it remained that way. Then it started humming quite noticeably (and the hum is amplified through the driver).
By comparison, the other SA1000 I have is still extremely quiet.
Having run a bunch of the usual tests on it to rule out other problems (like ground loop), I'm certain it's a problem with the amp itself. I read somewhere - regarding a different amp - that defective or worn "filter caps" may be to blame and that these usually can be replaced.
Has anyone ever replaced filter caps on an SA1000? If so:
- could you please indicate which parts you used as a replacement;
- whether a relative novice like me (with some, but not a lot, of soldering experience) could do the repair himself; and
- how well it worked out?
Thanks! :salute:
