Those who do so are living decades in the past, flushing their money down
the toilet, and decreasing the reliability of their rectifier unit.
The epoxy-potted diode stack manufacturers stopped using shunt
"equalizers" at least 20 years ago.
---On page 11.9 in the 1997 *ARRL Handbook*, it says: "In fact, shunt
resistors can actualy cause problems because they can produce a
low-impedance source of damaging current to any diode that may have
reached avalanche potential. "
