According to my old notes it's a BA11-SB, so 9 slot with H7861 power
supply. The block at the back has part number H403-B, no fuse holder,
just the main on/off switch and another switch held in place by a
plastic plate. Based on the inscriptions on said plate, I'm guessing
the latter to select the required line voltage.
