Dayton Audio SA 1000 subwoofer amp - repair

Good to know. One of mine was in protection mode just last night, the light was red instead of blue. Immediately turned it off  then back on and the light stayed blue.  It's only 3 years old. I think what he means by boat anchor is not worth repairing a $500 amp?  But a cheap cap is nothing to fix.  Has anyone else had problems with these?  

Good job!! 

We have become such a throw away society. Why bother fixing it..."just get a new one" is so much easier. Consumerism and planned obsolescence are part of the design. So many devices can easily be repaired but get conveniently dumped instead.

We used to have 'shop class' in High school. There should be a class that teaches the skill of trouble shooting and repair of these common problems around the house. Kids aren't taught this. Instead, they are taught to call a repairman to come do it for them as they sit there 'doom scrolling' on their I-phone.

Heck, I even remember, back in the day,  when we would do service on our own cars. Imagine that!

Love posts like this.  Nice work in seeing this repair through despite very unhelpful tech support through Parts Express.  FWIW I have found their tech support a crap shoot.  Sometimes excellent, other times not.

Thanks for sharing this easy fix.

One of my Daytons is acting up again, I  had it on the other night and 5 minutes later it was off!  Shut itself down. Before this the blue light was red when I just happened to look at it, as I stated above  in a previous post. I want this amp to work need it to work.  You think it could be that 2 dollar cap? Not much out there on repairing these, I couldn't find anything other than @steakster  post above. 

@brunomarcs My SA1000 didn’t shut down. It remained on with a high-pitched hum. Take the cover off and check for bad caps. Either leaking or swollen. Though the cap in the C6 position looked fine, replacing it fixed the problem. Good luck!

Mine didn't make any noise and I tried it last night and it worked, only used it for a minute or two shut it down, I want to repair before using again. Thanks. 

Mine simply died. Looked inside and saw some spatter and some black burnt looking tiny parts on one of the 'cards' not sure what all is blown.

Even though it`s still in production they won`t sell any parts to make repairs.

Parts Express were NOT helpful. I even sent pics. I asked if I could just buy the 'card' which is about the size of a credit card.

It`s a shame that it`s been rendered a heavy pile of junk for probably 89 cents worth of parts that they wont sell 

I've opened mine and don't see any leaking or bulging caps. Don't see anything that jumps out at me. I've powered it up without anything connected and am gonna watch to see if it goes back in protection. If these are gonna be unreliable I'll start looking for something else, I have two of these in use 3 years now. 
I wouldn't even bother to contact parts express, I bought one on Amazon and the other from parts xpress, it was cheaper than parts xpress.  During Covid even these were hard to get. 

I just read where they have a 5 year warranty 

There`s no work around for repairs or parts other than figuring out what all is bad and fixing it yourself.

They don`t service them they replace them AFAIK 

The amps don`t have a very good reputation IMO

I went to a Crown XLS. I might put the Dayton on ebay for parts.

I let mine idle for 8 hours without issue maybe I have something amiss with a cable. 

The Dayton amps are disposable.  Manufacturers/ brands like that have no provisions for parts or repairing of those units.  They either become a doorstop or it's up to the end-user to fix it.

As mentioned above, a Crown offering is a much better option.
