The AD30VT cabinet was constructed of particle board covered in traditional Vox basket weave vinyl. It included a 10" speaker of Oriental origin. The speaker was stamped with the model number "AD-30" and a manufacturing date code. The date code stamped on the speaker shown above was "C0803," suggesting an August 2003 production date.

Neither the Vox Showroom or North Coast Music accept responsibility for personal injury or damage to your amp while performing these steps. Proceed at your own risk.
Unplug the amp from the wall. Remove the wires from the speaker. Remove the eight large phillips head screws that secure the chassis to the cabinet and slide the chassis out of the enclosure. Compress the top end of the tube into the foam block until the tube pins clear the socket. Be careful to not shatter the tube.
