To remove the power supply unit from the cabinet, unscrew the four
screws at the side of the rear panel of the unit and w i t h d r a w it, un-
plugging the audio output to the bass unit. (If the 701 electrostatic

remove this, by reversing the assembling instructions which follow.)
The various adjustments to the mains voltage selector are self-
explanatory. Re-insert the power supply unit into the cabinet, securing
by means of the four screws.
Final Assembly. Having made the checks, and adjustments, if
necessary, the 701 electrostatic unit may now be fitted. W i t h the
cabinet secured to its stand, the electrostatic may now be inserted
into the sockets on the top of the cabinet. Spigots on both feet of
the 701 locate in corresponding sockets and they can only be assem-
bled in the correct manner. Having inserted the electrostatic unit,
make it secure by screwing down to the cabinet through the hole in
the rear of each 701 foot with the screws provided.
