Only $5 for 10 PCBs and every new member get $5 bonus. + Express 24 hour / 48 hour service on [ Ссылка ] The Saba Meersburg 100 has a set of simply amazing speakers. The sound that they produce is legendary, so what better than to add a Bluetooth receiver to it and really enjoy the sound?
I used one of my Bluetooth adaptor PCB's that also includes a gain stage to boost the signal. The mod is completely and easily reversible, so purists can relax and forgive the intrusion, while others can enjoy the benefits of having an amazing tube-powered speaker system for their music.
Hope you enjoy the video.
I have shared the Bluetooth PCB project on PCBWays' website so that you can order your own boards, should you so wish. The link to these boards is:

NOTE:
1) A better op-amp choice would be a TL072 or NE5532.
2) The dual supply will not be +-9V, but rather closer to +-7V, which will work fine with these op-amps, but ...
3) Use an Rf of 33k rather than 47k, as some clipping can occur with the higher gain.
