See my vid of this circuit:

looks like a joule thief circuit
@guruji: very interesting, I would like to build that circuit.
Could you please post a good photo of the book page. In your video one can not see much. You could also post more information about the book, like title, author, publisher, which page.
Greetings, Conrad

Hi Tagor what book are you refering to? The book I'm showing on the vid is just schematics that I printed from the net. :)
That is the circuit I used. Yes it's like a JT. It's amazing that this circuit is that old.

??? The circuit you posted is obviously bogass. There were no transistors in 1913.
