I have no background in electronics but I'm really interesting in DIYing raspberry DAC with integrated amplifier. I followed the reference [url]http://www.raspyfi.com/building-my-reference-dac/[/url] and ran into some problems.
I want to build an DAC with integrated amplifier. however, it is difficult to find a proper power supply that would supply all my components altogether.
I have a 24V 1A small tube amp and i need a power supply that could feed my amp as well as three other 5V 1A outputs (xmos microcontroller, raspberry pi and the DAC).
I’ve been looking for such power supply but ended up finding ones that were either too expensive or too big. My question is, is it possible to have multiple power supply sharing one cable to wall power socket? If this is not applicable, can I just buy a high voltage/watts power supply then split the power into my amp and other components separately? If so, what sort of module am I looking for?
Sorry for asking these stupid questions as my knowledge to electronics were very limited. I’ve read the other post regarding the similar issue but the project in that post only requires two power output. I would also like to ask whether adding step-up/down module produces jitter or unstability In the system as it is ard to find power supply modules with 24V and 5V outputs.
