Default SOS

the dac was singing with all new components but NE5532.
then the Brown dog came today. I soldered it to the OPA827, sooooo exited ... put it in the system but only hummmmm! the opa got very hot too.
I put the NE5532 back on board. but only noise, very low comes out of the speakers now!
I must have soldered the OPs wrong or they got damaged during the operation or? Although I was connected to the water pipe....

the question:
is the AKM-chip damaged? and whole the board as well?
any advice?
crying ......

Nice suggestion Erin, these are probably as good as SMRs.

bad news Nosian...

yes, probably you have soldered them the wrong way....or mounted the browndog on socket reversed.

If so 12V regulators are probably fried...and opa827 maybe.

Leave the opamp unmounted and measure voltage on socket supply pins to check regulators.

I don't think the DAC chip has been damaged, the output resistors should have protected it....

What things do i need to change to a opa827. Could someone give me some URL`s :-) ? I need one opa827 right ? Is it safe to buy this on eBAY (original) but i don`t understand the browndog pcb ? Why are the BOM saying x2 ??

And do i need to solder the socket who comes whith the standard NE5532 in the DIY kit ? I am confused :-) Is there anyone who has i close up picture, of the opa/browndog mounted on the pcb ?

Hi, I have just replaced the NE5532 in mine with an LM4562 and was quite surprised how much better it sounded.

I also tried 2 of them in my old DAC, and that sounds a lot better as well.

In the UK I got the LM4562 for 3.54 post free, so well worth a try.

Anyone else tried the LM4562 ?

The DIL socket needs soldering to the PCB.

Silver88, "x2 on BrowDog", you need tow opa827. one on the dog another under the dog! quite difficult to solder I think. Already destroyed a pair! going to use LME49720 instead. only one needed!

But when i search for "BrownDog" on eBAY, this comes up : DIP8 Single to SMD Dual OpAmp Adaptor BrownDog | eBay

But i only need one pcb ? and the 2 x opa 827 ? Yes i read, but maybe if someone could post a picture or 2, showing how to solder the things right up, we all can try the opa827 :-)

this is the dog:
Single-to-dual Op-Amp Adapter (p/n 020302A)
you can see double sided pcb!
but I'm the wrong guy to show you how to do it. look at the Clave's photoes like here
