Well one fellow there says 50 to 100uF. Sounds reasonable and worth trying. Caps should be perhaps twice the battery voltage. I have a Rollieflash but am not sure where it is. I will look in my camera bags but may not have put it in one since I never use it. More anon...

Yes you are correct.

In this thread, someone addresses the value of a replacement capacitor for a flash bulb unit. Again, I have no idea how reliable this is

    handbooks. I am sure the cap is nothing special, especially
    since
    modern electrolytic caps use different chemistry than the ones
