I. INTRODUCTIONA few years ago (Winter of 2000 I believe) I picked upa number of high voltage multiplier assemblies andsome related parts from a local

junk box to find something more suitable for driving thecascades directly from the 60 Hz mains. In a dark cornerof my basement I found two matched AMP
