AC50 trolleys

Mark 1 - Type 1 - small box speaker cab

Single bar above the pivot wheel, basket for the amp to sit in with flat rectangular (rather than bar) sides and small uprights to keep the amp in place.

The Beatles on stage at Blokker, Holland, 6th June, 1964, and an advert from September 1964 - but the picture is old, as the advert actually advertises (and gives the dimensions of) the new large-box amps and cabs.

Mark 2 - Type 2 - large box speaker cab

Single bar above the pivot wheel, basket for the amp to sit in with rectangular (rather than bar) sides and small uprights to keep the amp in place.

The Beatles on stage at the Johanneshov Isstadion, Stockholm, 28th July 1964. And Vox amps lined up as prizes for a Granada TV competition in late September 1964. The two AC50 super twins have trolleys similar if not identical to the ones The Beatles briefly had.

Mark 3 - Type 3 - large box speaker cab

Double bars above the pivot wheel, basket for the amp to sit in also formed from bars.

Gene Vincent and The Londoners on stage at the Empire Pool, Wembley, 20th November 1964. Tony Hicks in Studio 3, unknown date in 1964.

Mark 4 - Type 4 - large box speaker cab

Double bars above the pivot wheel, parallel bars across the top of the cab for the amp to sit on.

The Hollies on stage in early 1965. Note the parallel bars (no basket) and the ball, rather than wheel, casters.
