    i'm sure i got it rite the first time as i spend considerable amount of time actualy sketcing the connections just to avoid any mistakes...but i think i'll spend more time on it tomm just to make sure....
    
    basiclly , i had pin 1( of DYN 1 ) soldered to pin 1 ( DYN 2 ) , pin 3 soldered to pin 3. These were then the +/- out. For +AC supply , it was pin 2 of DYN 1 and -AC , pin 2 of DYN 2. I had these drawn up correctly and compared it against the stock 4 pin case and it was identical and i worked fine when i turned it on. But i could be missing something somewhere....

      I don't know about the IXYS Isoplus-220 package. If it is all plastic then you are OK. If there is a metal plate on the back, the metal may be connected to one of the pins inside the package. This (or the heat sink) has to be insulated from any other metal parts.
