Quote from: altrez on March 02, 2010, 10:19:33 AMI think you are on to something that will prove to be a self runner.

Like maybe one coil bemf is powering LED and other coil bemf is returning all or part of the joule, or somesuch.  Quite amazing, really; like maybe the JT should have been designed this way, originally.  I still maintain that the B&E diode effect was originally causing more shorting, adding load.  If some of us can wrap our head around it... 

Thanks Kooler, major breakthrough.

Hi Kooler today I did your Bemf JT it works good but I am using a 2n3904 tr and consumes about 7ma. Maybe I should try those transistors mentioned Mpsa06 or Bc337 and see consumption rate.
Thanks

I have been using the same transistor, are you tuning with a POT?

Hi Stprue yes but using a 220k. Should I increase resistance pot?
Thanks
