Mount the transistor together with
the heatsink on the PCB, bend
the leads as necessary. Take
care that the metal back of the
transistor touches the heatsink.
Check that the leads of the tran-

The PCB can easily be mounted
into our housing type G403.
Due to heat dissipation, it is ad-
visable to make some 4mm venti-
lation holes into the housing.
Holes for the adapter jack and
wires will also be necessary.
