[Hallicrafters] SX-100 tuning

[Gerry Steffens]

Among other things I am a Hallicrafters collector/restorer.

I have 4 different SX-100s.  I have a mint specimen on a shelf above the bench and use it almost daily.  It is completely functional, alignment and calibration are about the best I have seen, given the dial markings (seems never off by even a full red line width).  From its history, I know it has been used very little.

All of these SX-100s are a little sluggish or more so in the mechanicals of tuning.  I have a couple of other radios with the flywheel or weighted tuning and they will coast down the band given a sharp twirl.  The above radio is the best of the four.  If one serviced the gearing, do these radios perform as some others, needing almost no effort in tuning and coasting down the dial given a sharp twirl?

I am attempting to decide whether to go in after the gear train.

Thanks,

Gerry
