€  Modern rectifier diodes require no equalization if they are similar to 
start with.     Old habits die slowly.    In fact, traditional 
"equalization" can lead to premature diode failure.  //  As I understant 
it   k2aw modules are made of 1n5408s that are potted in epoxy.   Potting 
increases thermal resistance and increases junction temperature.    I 
prefer to mount diodes on G10 perfboard since it affords optimal cooling. 
 //  Potted block rectifiers are more costly than individual units.  For 
example, a 10kV string of individual 1n5408s costs about $2.  .
