Hey all,
I’m starting my first Volumio project after I found an old T-Amp I built a decade ago (see images).
My ambitions fluctuate between reconstructing a BeoMaster 2400 with full control, to just stick it in a box and play with it a bit.
So I’m resorting to sticking it in a box and playing with it at the moment to get a feel for if I want to build something more proper in the future.
My electronics knowledge is limited. I know what components do what and I’ve built various circuits from diagrams, but never designed one myself.
For this I need two power supplies. 5v for the Pi and 12v for the T-Amp… What are my options?
Would it be best researching to build a rectifier circuit for a toroidal transformer, or just push in a 24v DC transformer and split/smooth?
I saw some cool stuff on crazy-audio, but he seems to be not selling stuff anymore. If there’s something that pushes out what I want, either ready built or as a kit, that’d be awesome, otherwise I’ll have to do a lot of research to make sure nothing is going to set on fire.
The module below has a dual 12V and 5V supply ready made. So far I have tested the 12V supply on a Class D mini-amplifier and it works fine, not tried the 5V supply yet though. I intend to use it for the Pi and the DAC I have in addition to the amp as a one box / one power supply combo (with Volumio on it obviously). amazon.co.uk/dp/B00HY3AA3S/r … B7RSJJN9MN
I have the small USB DC-DC. The output is relatively clean but not the best for audio purposes (ok, not that anyone would notice unless knowing it in advance, but still), but if you want a better solution, use a adjustable one set to 7V output and then use a linear regulator with ceramic and electrolytic caps to go down to 5V.
Use this one to go to 7V: dx.com/p/buck-constant-volta … -5a-239099
