The positive lead of a 10 uF, 25 V electrolitic capacitor is connected to R91. A small piece of wire is
soldered to the negative lead of the capacitor. This lead is connected to a 3.5 mm mono chassis terminal.
The chassis plug can be mounted on the metal plate above the VHF set's power connector. As this metal plate is connected
to the ground of the VHF set, no separate ground connection is necessary to the 3.5 mm chassis plug.
