Hi!
The old 800rb's have handles on the left hand side of the head, on the removeable side-panel. These side-panels unscrew, and are replaced with the reack-ear side-panels to be placed in racks.
Mine is an '86 model, and still has the original side-panels and handle on the left-hand side. Because the rack-mount side-panels aren't available any more (the modern 800rb's have removeable 'ears' like(ish) the 700rbII and 1001rbII) I have to carry mine in a suitcase-style roadcase when on the road.
Otherwise, the amp can be easily carried via the handle - convenient!
Thanks guys, gotta love the old 800rb's!
