Grundig 230

Surviving information on the Grundig 230 is exceptionally thin. The archive holds no verified fact sheet for this model: no identity, no production years, no specifications, and no original price. The model number appears in the Grundig catalog here, but no period directory entry, manual, or advertisement in this collection actually names a "Grundig 230." It is not even certain what kind of product it was — tape recorder, amplifier, radio, or something else.

The most promising lead is a period test report in Audio-Collection (p.55) that measured a Grundig power amplifier at roughly 50W into 8 ohms, rising to 150W into 4 ohms, with the protection limiter pulling the 2-ohm figure back to 70W. The reviewer found midband distortion fine but rising sharply at high frequencies, with some low-level intermodulation sidebands revealed. However, the surviving scan of that review doesn't show a model number, so connecting it to the 230 is an educated guess, not a documented fact. Other period references retrieved alongside the 230 concern the Grundig TK 6 and TK 830 recorders and the Saba TK 230S — none of them this model; Tape Recording (March 1958, p.6) reported on the TK 830's U.S. import.

Until a manual, advertisement, or review bearing the "230" designation surfaces, the Grundig 230 must be recorded as essentially unknown. Any collector holding documentation or a surviving example would be filling a genuine gap.
