cdonke Posted July 16, 2004 Report Share Posted July 16, 2004 As we can read in the image above, there is only on Trasistor (TR), but, at the schematic page smrtkit lists 3 transistors (BFR90, BFR91, BFW92).I'm a newbie in electronics, and although I notice they are diferent, I can't understand what is this diference...Datasheets:BFR90BFR91BFw92 Quote Link to comment Share on other sites More sharing options...

GPG Posted July 16, 2004 Report Share Posted July 16, 2004 They will all work in this circuit. The layout is far more important Quote Link to comment Share on other sites More sharing options...
InFLak Posted July 23, 2004 Report Share Posted July 23, 2004 I built this circuit. I think it is not very useful. Quote Link to comment Share on other sites More sharing options...
