[Hallicrafters] S-76 S-Meter Problem

[W4AWM at aol.com]

Hi Bob,

About your S-76 meter pointer getting stuck with wide excursions of the 
pointer, there are several possible problems, the most common being dust or 
dirt particles getting into the "works."

The easiest possible cure which sometimes works is to take a small 
screwdriver and gently turn the meter adjustment screw on the front of the 
meter housing through it's range of motion several times.  Often, this will 
dislodge any particles that have become hung up.

If this doesn't work, removal and careful disassembly of the meter is the 
next step.  After it is apart, check in the bearing area and in the area of 
the coil and see if there are any foreign particles evident.  Sometimes 
something metallic will stick to the magnet and rub the movement when it 
makes a wide swing.  Also, carefully inspect the pivot bearings and be sure 
that the movement is free, but not sloppy. Check the ends of the pointer to 
make sure it is not rubbing on a stop or the scale when it makes a swing.

Hopefully you will find the cause of the sticking problem with one of these 
steps.  Good luck and please post your findings here so that others might 
benefit from your experience.
