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):
