Hi
Background
I’m about to set up a new stereo setup with a oair of passive speakers and a old amp as well as a bluethoot receiver. The plan is to stream from phone to the receiver that transfer the signal to the amp.
The bluethoot receiver is powered by a 5V USB cable.
I’m having a open setup and want as few cables as possible.
Based on this I would like to mount a USB power plug in my old amp so that my bluethoot receiver may be powered by connecting a USB cabel to the amp.
Question
Does anyone know a USB plug suited to mount in a chassie that has 220V@50hz input (and of course 5V output)?

Neutrik chassis mount USB socket would do the trick, then just plug any old USB charger into it inside the chassis. Or even better build a linear power supply.

I vote for the Neutrik, but if You want it cheap use one of these and use an phone 5V SMPS.

You could also mount a 220V switched outlet on the amp and plug the PSU there.
Another possibility is to tap at the amp's PSU if there is a low voltage rail for powering
pre-amps or displays. A simple 7805 and two caps would suffice as the BT probably doesn't draw much power.
