Grundig TK-3200 (c. 1971)

The archive record for the Grundig TK-3200 rests on a single detailed review. Studio-Sound (March 1971, p.43) reviewed the "TK3200" as a battery-powered, half-track mono portable tape recorder. The manufacturer's specification quoted there confirms the format: half-track mono at 19 cm/s (7½ ips). The reviewer measured the response at 19 cm/s as essentially flat apart from a 2 dB boost in the region of 60 Hz, with 16 kHz already 1 dB down. At 9.5 cm/s the response followed a similar pattern, again with the 60 Hz emphasis.

The review continued on p.44. There the reviewer recorded that a 2,500 µF capacitor placed across the battery supply failed to make any improvement, apparently in pursuit of some unresolved power-supply issue. The machine's current consumption was also measured. Beyond that, documentation is thin. No original price, service manual, or further period coverage has surfaced in this archive, so the TK-3200 is known mainly through this one Studio-Sound test.

- Half-track mono battery portable tape recorder

- Speeds: 19 cm/s and 9.5 cm/s

- Measured response at 19 cm/s: near-flat, +2 dB around 60 Hz, -1 dB at 16 kHz

- Reviewer found no improvement from a 2,500 µF capacitor across the battery supply
