T402:
Install
the
prepared
transformer
in the
circuit
board at T402.
Be
sure
the black
wires
go into
circuit
board holes
3 and
4
and the
violet
wires
go
into
holes 1
and 2.
Then
posi-
tion
the
transformer
down
against
the
circuit
board
and
solder
the wires
to the foil.
Cut off
any
excess wire
lengths.
