tune in, turn on and win this

It’s pretty obvious that we here at Alphabet Arm love music, and that’s why our latest shirt “Stereo Schematic“, is an homage to the equipment that brings the celebrated sounds to our ears. To share our enthusiasm for the recording process itself, and to make sure you are looking fresh this Fall, we are giving away a shirt to the first person to answers the following questions correctly. That’s right – it’s a three-parter:
A. How may Flux Capacitors are pictured?
B. What is the typeface used in this design? (HINT: it’s our studio standard)
C. How many speakers are included in the schematic?
