I picked up a flash unit at a local thrift shop. As soon as I figure out a few things I'll let you know. So far I haven't been able to get a spark without the tube. I did scare the crap out of my wife when I discharged the cap with a screwdriver. Here are a few links I found here on Spudfiles....very interesting...

for some reason, with no tube, when contact is made where you trigger flash, i get a spark from ground to trigger wire. This is supposed to happen, but its dumping the whole main cap int scondary transformer. This gets a hot spark.


Try to make it dump whole cap into secondary transformer.

That was very nice but I thought it went a little fast. I bought a cheap throw away for the very same purpose but the insides didn't look like that. Is there a schematic for those of us who want to do this?

I do like the video approach, though. I wish I had something like it when I first built mine. maybe it would of saved me a few dollars.
