Recently, I've acquired a Canon Elan EOS IIe - and I intend to hook this into the synch of my DynaLite MX1000 packs. After a great deal of research, I've found that the synch voltage of the Dynas is 10 volts, and there is some concern over whether the Canon is designed for, or will be affected by that much juice (incidentally, after shuffling my feet over a carpet on a dry day, it is not unusual to fire the DynaLite synch circuit via static electricity). The only advice I've been able to glean from the web is that the Canon's use with DynaLites is regarded as "Iffy". Wein has voltage regulators that will limit circuit voltage to 6 volts. Questions: Are the Wein regulators worth the money - to drop four (4) volts? Does anyone beside Wein make comparable regulators? Does anyone have any experience with these, or any other regulators? I have an idea that this will make a lively topic.
