Hi there,

I am moving my way to order a few parts from you. In order to check I'm not doing mistakes and order everything at once, can you confirm I have in mind the correct poer diagram ?

I read on this forum you have some WM8805 mux in the pipe. Is this a dead project ?

Thank you
BR

Edit : Just found another Toroid power tranformer with the following characteristics
80 VA - 230VAC outing to 2x15VAC 1A + 3x9VAC 1.5A It should be better espêcialy when adding the Raspberry Pi (700mA) and the USB2SPDIF board (500 mA)

Power line diagram

With 80VA total transformer, I doubt softstart is required. Typically it's used for > 300VA transformers.
