Q: I plan to use this to drive piezoelectric tweeters at ultrasonic frequencies. What is the upper range of this amplifier?

The TI datasheet for the chip used in this amplifier shows about 28db of gain in a pretty flatline between 20 Hz to almost 40KHz. By 100KHz you lose about 6db of gain. So assuming their isn't additional RC filtering on your input signal. All bets are off with Bluetooth though. My guess is you are going to lose anything about the typically specified 20 - 20KHz using a bluetooth input just due to the ADC limitations.

Q: Do you know what size of nut I need for the volume nob? I need a new one

Bring the board to a hardware store and see if you can find one, but being such a big ID and small OD and super thin, you're going to be hard pressed to find one without ordering the specific potentiometer

Q: can you custom name the bluetooth device?

Yes on a iPhone you can! Go to blue tooth devices.... click the name you connected to ( when connected to the device) go to info and rename device.

Q: Why am i getting a buzzung when there is no music? Very small audible hum

I initially had a hum when I plugged into the headphone jack of my tv as well. I simply had to adjust the tv sound settings to Theater mode and the hum went away and the sound now works great!
