Brazilian zip code is very important

Because having zip code, pcboards will reach destination...zip code informs the town, the place, and the street.

So, having zip code, the name and the house number, or building number and appartment number..then everything gonna be all right.

As a tradition we inform:

Name
Street name - house number or building number
Appartment number (if building)
Location (bairro) place
Town
State
Country
South America

and the most important....the ZIP CODE.

regards,

Carlos

Costuma demorar mais de 15 dias Zimmer....já esperei até 1 mês pra receber coisas da Europa.

Once i wait 30 days to receive boards from Europe...not less than 15 days.

Abouth Switching mode power supplies (SMPS)

SMPS unit was not tested in my laboratory...so, for a whileit is not suggested, not appointed and have no support till i have one at my workbench to face torture tests.

Switching mode power supplies use to enter protect mode when we have surge of current.. some of them produces noises that can be captured and amplified messing with our sonics, some of them cannot withstand with more than 10000uf to each rail in the output, and this is needed to provide low impedance flow of electrons in order to provide you fast energy for peaks... some SMPS supplies are not fast enough to follow modern audio amplifiers, in order to correct output voltage... some of them if face 30 thousand microfarads each rail understand the surge of current when you switch power one as a short circuit and enters in protection mode and shut down.

If you decide to use..do it under your own risk.

Carlos

Click to expand...


I completely agree with Carlos about SMPS issues.


I will build my final SMPS in month or two, and by that time i will test them as per Carlos recommendations + testing at DX Amplifier.

Thanks

Postal strike in Brazil may further delay delivery of cards.
So as posted Carl, there is patience to get them.

thanks

Greve nos correios do Brasil pode atrasar ainda mais a entrega das placas.
Então como postou o Carlos, haja paciência para recebe-las.

Obrigado
