Grundig 2210 (1955/56)

The surviving records disagree on what the Grundig 2210 is. One source lists it as a Röhren-Radio - a tube radio. Another calls it a Kofferradio, a portable set. The specifications mention a leather case, so portable looks like the better bet. The tube complement shows it was a valve-era design, built for the 1955/56 season.

Electrically, it's a five-tube superhet with a rectifier, using Grundig's standard mid-1950s tube lineup. A pair of ECH81s handle mixing and oscillation. An EBF89 does IF amplification and detection. An EABC80 does audio detection and pre-amplification. An EL84 output pentode drives two speakers at 4 watts. The rectifier stage uses both a DY86 and an EZ80. It covers long wave, medium wave, and short wave, a sensible spread for a German portable of the era, when international broadcasting was still a major draw. Power is AC mains only, with voltage taps for 110/127/220/240V. Despite the leather case and the "portable" label, it was not a battery set.

The original German list price was 259 Deutsche Mark. Beyond that, the record is thin. No dimensions, weight, or frequency response data have surfaced, and no period reviews of this specific model have been located. Audio (June 1980, p.123) was still running classified ads for European-sourced speaker kits years later, but the 2210 itself seems to have slipped past the magazine reviewers entirely. What survives is the basic factory data: a leather-clad, mains-powered tube portable with shortwave coverage, built by Grundig at the midpoint of the 1950s.
