Grundig 3400
The Grundig 3400 is a reel-to-reel tape recorder, though documentation on it is thin. What the record shows: a three-head machine running 19 and 9.5 cm/s tape speeds, accepting reels up to 18 cm. It appears to have been a tube-based (valve) design, per Radiomuseum.org's categorization.
The specs are sparse, and the sources disagree. Hifi-Wiki lists a frequency response of 30 Hz - 20 kHz at 19 cm/s, while Radiomuseum.org gives 40 Hz - 20 kHz. They also disagree on motor count (three vs. two). Both conflicting figures are left out here rather than guessed at. Four separate databases corroborate the more consistently reported figures: three heads, 18 cm reels and the two tape speeds.
Beyond that, the record goes quiet. No production years, no original price and no user reception notes have surfaced. HifiEngine lists the model as "Grundig TK 3400," which may be the same machine under slightly different naming, but no source explicitly confirms that. A period review in Studio Sound (April 1967, p.43) described the related Grundig TK340 as a quarter-track stereo recorder with internal power amplifiers and side-facing speakers.
