As per its name, this tube amplifier provides an output power of 15 watts with 16 ohms impedance selector.

b) Minimal Size and Weight –

What amuses us about Vox AC15 is its perfect weight and amazing compact dimension. It weighs 48.5 lbs with 23.70 X 10.43 X 17.95 inches. That’s why it is easy to carry and attach this amplifier at any moment with any electrical musical instrument. However, this amp has got 2 strong EL84 tube complements.
