Hi Tim!
Noo, I visit the Forums at least three or four times each day. Don't be affraid, you're not alone, all of us are here.
Because at this days I'm testing, repairing and modifying an slightly old self-made electronic flash unit, I'm planning to test "at a real environment" your Amglo Open Spiral, despite its intrinsically high voltage requirements.
When I will have any results about I will share here the info. and eventually pics for you and anyone interested on.
Best regards,
M. Gonz?lez.
