To improve the DU-5 fitted on my 1927 Henderson De-luxe I decided in rebuilding it with a modern style electronic regulator. This in addition to improving the charging make it a two brush generator where the field is controlled by the regulator.
Such a modern style regulator is availiable from; http://www.splitdorfreg.com/
