A number of years ago I made a partially-rectified current setup for
consolidative reduction of silver (I believe).  I was able to follow
Robert Organ's excellent directions in his publications and the unit
functioned very well and did exactly what it was supposed to.  It
requires a selenium full-wave bridge rectifier which one modifies by
cutting one of the connectors.  I don't know if anyone even makes
selenium rectifiers any more (but there is always the surplus
market).  Contact me directly if you want further help.
