3000d Transformers Grounding Out!

[Zade08]

Ok guys I figured Id post a tut on this since I had the problem and was able to save me and db-r shipping money by fixing it myself.

What was going on is my saz-3000d kept randomly going into protect. it would play long and hard until it got bumped and would then go into protect. At times I could try and make it go into protect and couldn't. It finally downed on me that it must be a grounding problem when I kept getting a small pop in my 6x9s as I would tap on top of the amp in a certain spot. To sum it up heres the problem and the solution.

Problem: Saz-3000d transformers are set to high in the case. (This is a small trend from the factory) The transformers keep hitting the bottom cover plate and rubbing of the protective rubber coating. Once the bare metal is exposed the transformers where rubbing and grounding out.

Symptoms: Popping feedback to other amplifiers due to grounding out and short circuiting of the 3000d causing it to go into protect.

Solution: Open up the back of your 3000d and look at the back plate and see if there are shiny scratch marks above where the transformers are located. (Transformers are the big colorful donut looking things) If so then your amp is probley grounding out. Just go to the hardware store and pick up some kind of flame resistant adhesive rubber and just put it over the spot were the transformer is rubbing. You can also use a roll of weather stripping. I just used electrical tape.

Warning: What ever you apply to the spot try not to put an excessive amount as then you are just creating a fire hazard.

Pics after the jump.

Hope this helps and Im not responsible for any damages that occur or voided warranties with you attempting this etc. etc.

I've done that before to fix an amp - very very uncommon but an easy fix if you figure out that is what it is.

Actually Jake Iv had this problem for about 2 weeks now and couldnt explain it. I sent it back to dbr and he couldnt make it go into protect. (Go figure he probley left the back off to get monitor the internals) Sent it back and then I called Chris back and told him what it was doing. He told me he had this happen once before so i tried it and vwalla it worked. Not trying to knock sundown at all. I wouldnt trade a sundown amp for any other amp in the world. Great products, customer service, Price, quality, and performance. Best brand Iv ever owned by far.

That is what I said It can happen, albeit, it is very rare. I've used the same fix before.

pretty cool easy fix. but...you should flatten the tape out

[Zade08]

does this happen with the saz-1500d also, or just the 3k?

It can occur with the 1500D - the ONE time I did the fix it was on a 1500D.

Chris at db-r said hes only seen this on 1 other 3000d. Dont let it scare you. its just a tut in case it does happen you can save a couple $ and some time on shipping.
