I NEVER ground the frames of filter chokes, modulation reactors or 
modulation transformers.  It puts unneeded electrical stress on the 
insulation, which is often little more than paper that may be 60+ years old. 
  The rubber shock mounts I am using provide electrical and accoustic 
isolation for the swinging chokes, which tend to be noisy.  My mod xfmr and  
reactor are mounted on solid composition insulators.
