[Hallicrafters] SX-117 info

[Jim Wilhite]

According to the information I have the input voltage design was for 105-125 
volts AC so that should not be a big concern.  What may be more of a concern 
is leakage of the electrolytic capacitors in the power supply or any others 
that are in the set.

The transformer should be adequate for the receiver and will run warm.  Be 
sure the capacitors are in good condition and look for any other improper 
drain on the HV.

Looking for some first hand knowledge.  I just picked up a SX-117 with
matching speaker.  After replacing three tubes, and doing a cursory
alignment, I am VERY happy with this new rig.

I have a point of concern however -- it seems like the power transformer
runs quite hot.  My digital thermometer reads 149 degrees F after about
30 minutes of operation.  It doesn't appear to go past that, so I
suppose that is a good thing.  I'd appreciate anyone's thoughts or
experiences on that.  I will hook it to a bucking transformer to bring
the AC input down to 110 and see how that goes.

Second, the tuning dial has a bit of a slip in it.  It's only momentary,
and not reproducible at any specific point.  It also seems to diminish
after the radio has heated up.  While it isn't a problem now, if it is
something that can easily be addressed I'd like to deal with it before
it becomes a catastrophic failure.

I believe the one I have is the "E" revision.  I have the original
manual. Any recommendations that will improve longevity or performance
are greatly appreciated.
