I've heard that it's impossible to find T1. To make one self, you have to wind: Primary:3t 0.375 mm magnetic wire Secondary:175t 0.15 mm magnetic wire on a toroidial core

Why buy one from the shop? That's just boring, it's much more interesting to make your own.

Are there different levels of Black Light detection; if so , what are they and a few examples of items detected whithin each level. I'm mainly interested in phosphor and bacteria in/on clothing. thanks William

Transformer #G993 is out of stock at Electr. Goldmine. This seems to be a permanent condition.

Hello Can I get more info on the transformer? Like a part number or input output of the transformer How long is the tube or how long of a tube can I use? Can I use a white florescent bulb nested of a black light?
