only one 7
pin
socket
on the board,
)
D. Plug
the Tone
Module in
to the socket
and attach
it

The DC high
tension fuse is located
on the circuit
board .
This
is
a
feature
of
the
AT Amplifier,
which is
equip@ with
a current
limiting
circuit
preventing
excessive DC
currents,thus
eliminating the risk
of blowing high
tension fuses. In
the
unlikely event
that the high
tension
fuse actuates
,
the output
transistors should
be checked
,
as
it is
probable
the
amptifier has
been subjected
to
very
extreme
conditions
.
