This isn't an AC/DC set, it uses a small, low profile power transformer. You can (barely) see the top of it to the left, behind the 80 tube, in Jim's second photo.
Arran, the 620 and 625 cover the same frequencies. There are differences in the circuitry, chiefly in the AVC circuit. The 625 also has a moving shadow mask behind the dial scale, with three holes that allow the greatest illumination only to the band in use.
