This amp was spun from a similar vein as the original AC15, just with a simpler, more modern format. It features easier accessible 9-pin preamp tubes (12AX7/12AT7), as opposed to the more obscure EF86. This model was made in England by Rose Morris. It shows moderate signs of previous wear and still looks good. When pushed to it's limits the cabinet might exhibit a little rattle, but this is common of most higher powered combo amps from the era.
