[Hallicrafters] SX-42 S-meter blues

[Steve & Sharon Nordentoft]

Hi All,

Sadly, after a full cosmetic and partial electrical restoration of my SX-42, it's s-meter now reads erroneously.  I replaced the zero-set pot and doubled checked the circuitry.  After proper calibration using the pot, the meter will not zero down and only will fall to about 7 on it's scale.  One stronger signals, the meter will only peg at just above 40 on it's scale and the needle tends to be a bit bouncy.  I'm somewhat baffled since the meter was operating properly even after my re-cap job.  The AVC operation does appear to me to operate properly.  The meter seems to work properly when using the FM function.  I replaced the zero-set pot with a new 500 ohm, 3 watt part.   

Any suggestions from the group as to what to look for would be appreciated!  Thanks!
