I asked this before, but apparently I lacked sufficient details.
I have an old flash (strobe) from the early 1970s that runs off of an AC = adapter that converts 120vac to 455vdc. The flash itself has the = humongous capacitor in it's handle (about 5 inches tall and 1 inch = diameter) and a few other electronic components in it.
Now, I know for a fact (because it's an accessory listed in the brochure = and from browsing the various camera groups) that there was a battery = made by Eveready (No. 497 Carbon Zink Battery, listed as 510v but stated = clearly on the label that it only puts out 450v) that is still = available, puts out 450vdc @ 140mAh. Retails for $89.99 US, not = including shipping.
So, since the battery is sooooo expensive and NOT rechargeable, I = thought that there must be a simple DC-DC converter that would take = either a 6v, 7.2v or 9.6v battery pack and step-up the voltage to =
450vdc, so that I could use the correct power cord and plug it into the = flash.I have lots of circuits on the net that will take 6v, 7.2v, 9.6v and 12v = dc and bump it up to 250v and even 300v, but it is AC (although I assume = that I could use a bridge rectifier of the appropriate voltage to = convert to DC) and at least 150v shy of what I need.
So, is there a simple circuit to do what I want (I would think so)?
