Joule Thief

@ xee2:

I just checked real quick and mine is indeed marked T 9A on the side.  Maybe yous is an equivalent one they bought from another supplier?  Thanks for the info on troubleshooting.  I didn't spend a lot of time with it last night, ended up working a surveillance case until 7:00 this morning.  But, I did what you said and with one lead on and my touching anywhere near battery, it worked, with the other lead on, it did not.  So, this is my bad connection somehow.  It is soldered exactly at the point in the photos on Jose's site.  Maybe this weekend I can check the connection again.

@Cap-Z-ro:

I will test as you suggested.  Hey, you never know, maybe I screwed something up that will turn out to be a good thing.  Then, I can take credit for planning on doing it that way all along, ha ha.  Thanks for the input.

You know Bill, that probably was the case with more 'inventions' than we might think.

I checked the "99" transformer pin locations and they match Freezer's diagram. The transformer casing seems to be made of plastic.

Works per Freezer circuit. Brighter than Kodak but does not seem as bright as Freezer was getting, but I do not have neon bulb in parallel with tube. If you are still having trouble getting it to work - post photos of board near neon bulb (showing bulb), near diode (showing diode), and on other side of board near positive battery terminal, I will mark them up to show where to clip leads.
