RME-45
Y'all got it, of course.  Someone removed the anti-backlash
springs.  Cleaned the years of gooey from between the gears
with naptha (lighter fluid). Unlike the TCS anti-backlash gears,
these seemed to need lube so worked a few drops of light oil
between them.  Used a spring from a "click-click" 
ball point pen.  Half the spring on each side seemed just right.  

The small reduction-drive gear that engages the anti-backlash
gear was not worn (probably because the springs were missing).
A single tooth of backlash compression was enough.  
Once set, I put the tip of a jeweler's 
screwdriver in one of the teeth, gently twist to flex
the anti-backlash gear and pull the screwdriver out.
The gears should immediately rebound with an audible "snap."

Sadly, there is a bit of side-side "slop" wear in the 
reduction drive- something I can't fix.
So there's a bit of "wooble" yet on the highest band,
but nothing so bad as it was.  It's useable now.

Really enjoy this set, especially since toning-down
the wicked near 400V B+ to something sensible: 220V.
Cooler and more stable with no apparent loss in 
performance. It can actually hear things on 10 meters.
