The pre-amp uses the transformer as supplied by Yuan Jing and for the 3116 I'm using an Indeed 12V "brick", I have tried a couple of cheap generic bricks off ebay but they both produced so much noise they were worthless (for audio applications).
I have 2 of the Indeed pwr sup's now and can highly recommend them.

Thanks for the info...I'm partial to switching PS from Genssi, but you need a large enclosure and economics sometimes come into play.

Hope I haven't already shared this: TPA3116 in a $1.99 Ikea picture frame case bolted to an Astron linear regulated PS.
They are DC, not AC . I use Sure boards, which are DC. Usually I use 36VDC 9A. Here is a link: http://www.amazon.com/Genssi-Regulated-Switching-Power-Supply/dp/B005CLCJA6

Nice little cast aluminum case found at the Goodwill. 😉. Cheap Lario 30-pin adapter ($15 on Amazon) supports Internet radio with TuneIn Radio via AirLino android app, plus AirPlay and UPnP.
