Grundig TK 147
Pure luxury: stereo tape recorder TK 147
If one reads the type designation of the Grundig TK 147, one expect probably a direct successor of the TK 145. In fact,
the two devices resemble each other. The drives of both tape recorders are also very similar. The TK 147 is a fully
transistorized stereo device, while the TK 145 is still equipped with tubes. Apart from the fact that it is a stereo device,
on the TK 147 the user is looking for some luxury equipment in vain. The advantage of the automatic recording control
also led to the fact that this device is missing the pointer instrument. Its place is filled out by the letters "AUTOMATIC",
which are illuminated during a recording. Otherwise you are looking for nice gimmicks in vain. On the left, five buttons
and two controls to control the most necessary functions. On the right is the lever for the drive control, similar to the TK
145.

- Page 2 In the true sense of the word, all drive functions are in one hand. Here again a look at the knobs and controls of the TK 147. To the left the track switch with the additional button for the stereo operation is, to the right the volume and tone controls are placed.

- Page 4 The two handle holders can be simply turned out with a slotted screwdriver. Now the housing of the TK 147 can be pulled carefully upwards and the chassis of the device is left over, as can be seen in the picture above.
- Page 5 When I got the Grundig TK 147, it had a very common error known as normal in devices of this series. The knob for the drive control was in the rewind position and couldn't be moved away from this position. The reason for this was the small white part in the foreground of the picture.
- Page 6 I don't know for what it is used. This is what the Grundig TK 147 looks like when the floor slab is removed. All in all quite clear, one could say. As with most devices, the drive motor, which also serves as a power transformer, is located at the center. To the left is the power amplifier board.
- Page 7 Here again a look at the power stage of the TK 147. To the right in the picture is the large heat sink for the final stage transistors. The rectifier is located to the left of the circuit board.
- Page 8 The Grundig TK 147 during a first test with a pre-recorded tape. After a thorough cleaning of all parts in contact with the tape, the sound reproduction was clear. Even all drive belts are still in a perfectly usable condition. I'm always amazed at how long these drives are workable.
- Page 9 Of course, I also cleaned the housing thoroughly before the assembly took place. In any case, the repair of the device was worth it. Now the TK 147 workes perfectly, and also the playback is clear and clear. The automatic recording level...
- Page 10 Grundig's 100 series were the successors of the equally successful 10s and 20s series (TK 14, 17, 19 and 23 and 27). There are certainly no high-end tape machines, but you were made relatively cheaply manufactured and offered. After all, the manufacturer Grundig was able to produce relatively inexpensive tape recorders, which were also affordable for the normal consumer.
