110 volts. If it is necessary to remove the cover, pull out the mains voltage cord out of the wall socket. The cover it
must never be forgotten to put it back into operation before connecting the mains voltage cord. In case of accidental
touching of the fuse holders, a dangerous electrical shock can occur.
The Grundig TK 147 with housing top removed. This unit is somewhat different from most other tape recorders. It does
not have a single removable housing cover. Instead, the complete housing is removed, leaving only the chassis and
the base plate. The disassembly takes place as follows:
First remove the five screws on the top of the unit. Then the knobs of the two knobs and the rotary knob for the drive
control have to be removed. The small cover on the back should not be forgotten. It is fixed with only one screw.
Before the housing part can be removed, the handle and the retaining screws must be removed. The carrying handle
is first pushed slightly towards the housing. The best way to do this is to place the device as if You wanted to carry it
on the handle. In doing so, the handle is carefully pressed downwards and then pulled out on one side, then on the
other side towards the outside. 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.
The tape guides and heads of the device. Here a thorough cleaning was necessary. In the foreground the control light
can be seen, which illuminates the word "AUTOMATIC" when recording.
