Re: 16VAC 1000mA PSU compatible with NAVA?

Hi,

That 16VAC wall wart will do fine. Before I made an internal power supply I used a 16V AC wall wart from an old router. Works like a charm.

Re: Internal->External PSU mod

I think the easiest way for you to go is to go back to the original design by Vincent. Use the external power brick. You will be perfectly isolated from the mains. And probably have no hum/buzz. Reason why some people go for build in power supplies is reliability. You don't want that flimsy 16V plug...

Re: Internal->External PSU mod

The only purpose of a groundloop breaker is to avoid ground loop hum when you interconnect different audio devices together with all of them connected to mains.

Yup, all back to what it was. Ignore the schematics. ;)

Re: Power supply

Hi, if it is a power supply with big transformer in it(so not a switching one), you can open it up and remove the rectifier circuit after the secondary and connect direct to the transformer. Make sure you check the voltage before you connect it to your Yocto. Anything between 15-18V AC should be fin...

Re: Internal power supply and PSU mod

Normally not, but if you can, maybe try to route the cable behind the electrolytic capacitor on the picture to the right?

Re: Internal power supply and PSU mod

So the 18.2 volt is what you measure when there is no load attached. This is perfectly normal, no need for resistors. Indeed the 0V centertap goes between C5 and C7 on the Yocto! (I'm into my Nava for the moment, so hence the mistake) Your pictures show the correct connections. Here is a detail of w...
