from sliding laterally. Carefully thread the diode wires out of
the
PCB
cavity through the access hole.
5. If replacing the C-mount
TA
diode rather than the
MGM-068
copper
block assembly, remove the old
TA
by desoldering the cathode ribbon
from the turret pin, then unscrew the M2 screw holding the anode
wire. Replace the indium foil and assemble with the new
TA
diode.
Ensure the
TA
diode is square and sitting flat on the copper block as
you tighten the M2 screw. When soldering the cathode ribbon to the
turret pin, use low-temperature silver solder. Do not resolder until
the
TA
diode is firmly attached to the copper to act as a heatsink.
6. Install the new
TA
diode mounted on the
MGM-068
mount by fol-
lowing the steps in reverse, taking care to replace the dowel pins
and threading the diode wires (which have crimp terminals but no
connectors) through to the PCB cavity. Ensure the H-clamp is re-
installed using a cross pattern to tighten the screws so that tension
is evenly applied as the clamp engages. Return the lenses to their
approximate position and secure the lens locking rings.
7. Insert anode (red) wire crimp pairs into the connectors until they
