WDHD3S Kit Assembly Instructions
Fit the earth terminal to the rear of the case. If necessary
remove some of the paint around the earth terminal hole so that
the terminal makes electrical contact with the case. Remove the
earth terminal binding nut and fit the terminal using a serrated
washer on the inside of the panel. Tighten the nut fully.
Fit phono sockets to the rear panel
-
red towards the bottom of
the amplifier, and black towards the top. Fit the solder tags so
that each pair of tags point towards each other and bend them
away from the chassis. When you have tightened the nuts fully
check with a continuity meter that the phono plugs are
electrically isolated from the chassis.
Fit the potentiometer to the front panel using the washer and
nut provided. Scrape some paint away from inside the chassis to
make sure that the body of the potentiometer is grounded.
Fit the headphone socket to the front panel using the washer and
nut provided. Offer up the front panel to the chassis to make
sure that the socket sits centrally in the hole in the fascia,
and adjust if necessary. Note that the PCB star earth will be
connected to the chassis via the headphone socket
-
it is
important to scrape some paint away from the inside of the
chassis where it meets the socket. Tighten the nut fully and
check for electrical continuity between the body of the socket
and the earth post.
Fit the power transformer using the mounting kit supplied.
Insert the bolt from the underside of the case, then fit a pad
to the inside of the case followed by the toroid, another pad
and, finally, the top plate and nut. Align the toroid so that
the secondary leads (Orange / Orange / Yellow and Red / Black) lie
closest to the PCB position. Tighten the nut to clamp the toroid
firmly in position.
