I could not believe the quality of the sound out of this miniature pcb when I connected my cell phone, via bluetooth, to my stereo tube amplifier! The supply is a hefty 12V 9800mAh ion lithium rechargeable battery come into manners with a parallel 78L05 voltage regulator that feeds the circuit with the 5V, 20mA that the circuit needs. Absolutely in love with this super small and inexpensive circuit!
