Replacement of Parts Supported on Ceramic
Bars
Usual soldering bits or the so-called soldering
guns can be employed when replacing parts
supported on ceramic bars. The metal coating
in the bar must withstand at least tripple
soldering. Frequent soldering may cause
the metal layer to peel off which makes
any further soldering impossible. When sol­
dering, proceed according to the illustration
below.

RC Tube Replacement
Dismount the tube frame, graticule, green filter
and the black shade inserted into the tube
shield from the face of the instrument.
Remove the top cover of the instrument.
Withdraw the tube base from the holder and
loosen all the connections to the CR tube.
Loosen the screw in the hole in the tube shield
near the base and push the tube out in the
direction of the frame by applying a moderate
pressure to the tube base:
When reinserting the tube, proceed in reverse
sequence. Care must be taken when installing
