[Hallicrafters] SX-117 info

All --

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.
