I think the circuit could work with ...Hello Johan, <br />I think the circuit could work with many transformers, as long as it has a primary coil (probably split in halfs or with a center tap, I use them in series), a feedback coil and a secondary coil. The secondary coil will have to have many more windings to give the right amount of voltage multiplication. Pay attention to the right "phase" of the windings, otherwise the oscillator won't oscillate ;-)<br /><br />Re. the transistors: others will probably work too (it's just an oscillator circuit working at around 50-60kHz), but I got the best results with this type.<br /><br />Good luck with building and let me know your results please. <br />RGRad Goeshttps://www.blogger.com/profile/07008530959417438036noreply@blogger.comtag:blogger.com,1999:blog-8570254661784965020.post-65017863184334714822011-06-18T18:04:49.990+02:002011-06-18T18:04:49.990+02:00This seems to be a very nice circuit.

I picked up an inverter from the junkbox here and it has the same amount of pins (6 primary, 4 secondary) and looks practically the same.<br />If those xformers are the same, I am going to pickup some of those transistors, zeners and fuf5405 and get soldering :)Johanhttp://www.julietmikebravo.nlnoreply@blogger.com
