Originally, the AC-50 "Small Box" speaker cabinet was perched upon a chrome rigid stand. The amp head sat on the floor, inside the base of the stand. As the Beatles played through these amps for their first US concert at the Colisseum in Washington DC, this version of the AC-50 has come to be known as the "AC-50 Washington DC'' amp.
Several month later, the Beatles were issued a revised version of the amplifier. The former rigid stand was replaced by a new swivel stand that allowed the speaker cabinet to be tilted and placed the head at the top. The Beatles used this version of the AC-50 in their June 1964 tour to Hong Kong and Australia. This version of the AC-50 small box is often called the "AC-50 Small Box Australia amp."
The North Coast Music recreations of these cabs are faithful to the original designs. The AC-50 "Small Box" speaker cabinet is constructed of 13 ply baltic birch plywood and includes one VAP-074 handle, an original style Switchcraft 3 pin jack with a 20 inch lead wire and the correct logo. It is covered in authentic basket weave vinyl and features brown Vox diamond grill. The cabinet is available with or without Celestion Alnico blues. As Goodmans Midax horns have not been produced in over forty years, none are offered by North Coast Music. One can only look in online auction web sites, such as eBay, to find these. Outside dimensions: 27.25" x 20.25" x 10.375".
The AC-50 "Small Box" head is constructed mostly from 3/8" thickness baltic birch. Like the original, it is covered in basket weave vinyl and features brown or black Vox diamond grill cloth. An VAP-074 handle is provided. Outside dimensions: 19" x 6.25" x 11."
