I previously designed and built a PCB to provide power to a Bluetooth receiver module, and serve as interface to a tube radio. The challenge is to isolate the supplies, to avoid the characteristic high frequency buss that these modules tend to produce. It worked very well, except that the audio level when inputting through the phono input was a little low. I needed a booster for the signal, and this project does just that. I have shared this project on PCBWays' website so that you can order your own boards, should you so wish.
