Make a connection-cable according to picture-1
- for the PTC-side with a 5-pin DIN- connector.
- for the TRX-side with 4 soldered wire-ends plus the twisted and soldered
You can use a normal DIN-cable, if all pins are wired and shielded.
Take off the bottom-cover and the top-cover of the TS-50 case.
Take off the front-panel (4 screws)
Carefully pull off the grey contact-band (left side of picture-2 rising
into the air) from the socket on the TRX-side (not the front-panel-side)
Put some bits under the body of the TS-50, so that the front-panel
lies almost flat. Like that the mic-socket is best accessible (picture-3)
Now read first about the assembly
Solder 4 wires according to picture-1 and picture-4 to the mic-socket.
GND is the shield of the DIN-cable.
The wire from pin-5 of the DIN-connector ( power-supply for the PTC)
will be connected to 12V inside the TS-50.
That is in the filter-unit at the fuse, which is used for the external
To do so open the cover of the filter-unit ( in picture-2 you can see
the relays and the coils of the filter-unit)
Solder one end of a "shielded wire" to side A1 of the fuse.
Solder the other end of the "shielded wire" to the wire,
that comes from pin-5 of the DIN-connector (picture-4: black wire)
Solder the shield of the "shielded wire" to ground.
That is at the foot of the HF-connector next to the fuse.
(picture-5 between fuse and tuner-connector)
The shield at the other end of the "shielded wire" gets no
