    Can you now open the manual in Adobe? The datasheet of the 2sc3964 only shows a minimum Hfe of 500 albeit at a different Vce and Ice so in my opinion it's OK but then I know nothing of these things http://www.futurlec.com/Transistors/2SC3964.shtml

    Design bass amplifier

    Whonoes, correct it can be used to create a sub woofer. I was generalising. But for creating a sub woofer your first choice of speaker will not be a 6 incher. Much easier making a decent sub woofer with nice tight bass out of a 10 incher.

    Make your PC Power supply last- 73's de Edd

    I hope 73's de Edd cruises by this thread sometime. I'd like to know why he uses bakelite discs for insulation and if I can use a rubber disc cut from an old bicycle tube.
