Jim,
       Interestingly, apart from studio flashes, almost all on camera flashes 
nowdays use 330V, with a few running at 350V.  I do have an antique Metz 
(seperate power pak)  which runs 550V as does an older Sunpak Ringflash I 
have.  
        I had some correspondence with Quantum on this and they indicated 
they only make turbo-z power paks in 330V. In talking with a far Eastern 
capacitor vendor they indicated they only make 330V and 350V photo-flash 
capacitors as that is the bulk of the market.

       Regards,
        >>Tim Hughes<<
