| − | == Remarks ==
| |
| − | 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.
| + | == Bemerkungen == |
| | + | Erstes Gerät nur mit Transistoren (21Stück), Bauweise wie [[Grundig TK 245]] |
| | | | |
| − | Both stereo channels are controlled together via ONE control.
| + | == Bilder == |
| − | | |
| − | 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.
