TONES NOT PRODUCED ON LIGHT BLOW
This condition is caused by hammers letting off too quickly, or
too far away from the reed (see "Touch," page 9).
SHRINKING ACTION
Please refer to page 12 of Wurlitzer Piano Service Manual. How
ever, before shrinking action centers, turn the instrument on
for several hours. The heat from the amplifier may dry out the
action sufficiently to make shrinking unnecessary.
CENTER PIN REPLACEMENT
Please refer to page 16 of Wurlitzer Piano Service Manual.
ADJUSTING AND CHECKING
REEDS
If a reed should need tuning at any time, it may be taken care
of by a piano tuner. The only difference in tuning is that in
stead of pullin� a string up to pitch, the tuner will be tuning a
vibrating reed {see Fig. 5}. If the reed is flat, the pitch may
be raised by removing some of the lead at the end of the reed by
scraping. If the reed is sharp, it may be · ·-
tuned by adding lead
to the end of the reed.
Adding weight to the end of the reed is the better method and
should be used if possible. Filing, unless expertly
done,
can
ruin the reed by weakening it and removing the protective coating
which keeps it from rusting.
Should it be necessary to remove or repair a reed, first remove
the shield (No. 24, Fig.6) by removing two screws. The reed can
then be taken out by removing reed screw (No. 27, Fig. 6). The
reed can be replaced or a new one installed by carefully watch
ing the spacing between the reed and the pickup (No.
25,
Fig. 5&6)
when tightening reed screw. See paragraph on Tone Producing
Principle.
