How long does it take

[jedidog]

I placed a order with audiosector going on two weeks ago and still haven't received anything how long does it take to ship from Canada to u.s.? i even sent him a email about it and got no response.😡

It depends on the shipping method.
I send stuff from UK to USA/Australia and it gets there in about 9 days best case.

Did you receive it now? It takes approx 7 business days for US and Europe deliveries.

 

[jedidog]

Yes i recived them . Really nice kits and sound good only thing is I build the second board just like the first one in stereo mode and the chip gets really hot fast and their is a allot or hum noise going three the speakers the first board I put together is dead silent

 

[nigelwright7557]

Probably a component in a wrong hole.
Or maybe a solder bridge somewhere.

 

[jedidog]

Nope I triple checked everything
