This is an old thread but I will post anyway....someone may benefit from it. I run a Vivitar 365 on 12v transformer which I built from an old battery charger. The flash is a powerful beast and contrary to popular misconception, it runs on 365 volts DC (hence the model name Vivitar 365). The DC transformer puts out 20 Amp and the flash is happy with about 10 Amps when charging the large capacitor after full power discharge. Recycle time is just under 4 seconds after full power discharge, on auto setting it can keep up with my Nikon D2X (about 6 fps). I also run the system on 12v 15 AH SLA with no issues. Its perfect for location shoots or to overpower the sun if used with High Speed sync remote trigger. An absolute bargain at only $5 dollars I paid for the flash and total of $15 spent on modifications to suit my needs. Highly recommended
