Grundig Stereo Tape Recorder TK 247
General
- Manufacturer: Grundig-Radiowerke mbH, Fürth
- Model: TK 247 de Luxe
- Type: Suitcase reel-to-reel tape recorder for horizontal operation with built-in stereo loudspeakers
- Years of manufacture: 1967-1969
- Manufactured in: Fuerth
- Color: metallic grey
- Remote control: no
- Power supply: 110V-240V, 50Hz (60 Hz with conversion kit)
- Power consumption: 50 W
- Dimensions (W x H x D): 450 x 200 x 340 mm
- Weight: 13,5 kg
- Original price approx.: Org. invoice JAN 1968 for 598,- DM
Connections
- Number of outputs: 3
- amplifier 2x 800 mV/22kΩ
- Headphone/amplifier monitoring control DIN
- Loudspeaker 2x 4Ω (supplement or replacement of the 4 built-in loudspeakers).
- Number of inputs: 3
- Micro 2x 1...250 mV at approx. 100 kΩ.
- Plate 2x 30 mV...7.5 V at1 MΩ
- Radio 2x 1...250 mV at approx. 32 kΩ
Technical Data
- Max. Coil diameter: 18 cm
- Drive: 1 motor, friction wheel drive, fast forward/reverse by belt drive
- Heads: 2 heads (erasing head and combined recording/playback head)
- Tracks: 4 (quarter track)
- Tape speeds: 9.5/19 cm/s
- Rewind time: approx. 270 sec. with LS tape 18cm reel
- (synchronisation fluctuations):
- Pitch fluctuations:
- <= +- 0.15 % at 9.5 cm/s.

- >= 48 dB at 19 cm/s
Special Features
- Stereo power amplifier of 2x 4 W / 5,5 W with 4 speakers (2 per channel)
- Automatic STOP at the end of the tape
Remarks[edit]
The TK 247 and the TK 241 (mono) were the only fully transistorized units from the 200 series until 1969. The design is similar to the Grundig TK 245, is 4 cm wider (more speakers) and the level controls are newly arranged.
Special features: The automatic recording tuning out of the TK 245 was omitted.
Both stereo channels are controlled together via ONE control.
Note: the mains selector switch was supplied for 220 volts. Since 1987, however, the mains supply has been 230 volts, and the selector switch should be changed to 240 volts with a coin (photo) - to protect the unit.
Other models for comparison[edit]
Models similar to each other until 1969 for horizontal operation (tubes TK 245 + full transistor TK 247):
Models of the vertically usable successor series from 1969 in a completely new design, technically of higher quality (e.g. 3 tone heads):
