Pickup Head
Model
D 22-1
Part Number 11481
Trouble may be experienced with the D22-1 pickup head due to instability of the
armature centering adjustment. Improvements have been made in recent production
to minimize this condition by decreasing the diameter of the centering spring and
making a more substantial attachment of the same spring to the pickup armature.
These later heads should give no trouble, however, if your observations are to the
contrary a report should be promptly made.
The improved head may be identified by inspection of the armature and centering
spring arrangement. The spring is looped around the armature and its end hooked
around its straight portion.
When unstable adjustment is obtained with the original type of pickup the complete
head should be replaced with one of the later improved type. The original heads
should be accumulated for return to Camden on a Field Removal Tag for credit.
