A modern unit of the same ratings will generally be somewhat smaller than the original. Get one of the same or greater voltage rating and roughly the same number of microfarads. I think something like 50-100 microfarads would be normal. The batteries for these tend to be expensive, if you can fit 2 or 3 nine volt batteries in series in there it could be a lot cheaper.

I have not tried it, but I would think that a single 9V would work fine. Those bulbs were usually triggered by a 3V source. The 22.5V with capacitors increased battery life and reliability, generally only needed for the professional and high use amateurs. Peter. -- Joseph E. Meehan 26 + 6 = 1 It's Irish Math |

I can't remember what the nominal firing voltage is, but at low (maybe out of spec) voltages they take longer to fire and are inconsistent. At higher voltages you don't have this problem. It might be that 22V was used to fire several bulbs in series or over long cables consistently. I've only worked with the bulbs the size of a standard GLS bulb. I can't remember the specific type. If one bulb over short think cables using a capacitor I agree with the above poster, it would probally be fine. Pete |
