    amping with a step down transformer

    Has anyone ever got something to be louder with a step down transformer. I imagine if u start with fairly high volts, and go into a small load, it can actually make it louder?

    constant current source with transistor

    So I just drew up another circuit, do u guys think this would work? Its two power supplies, one for the base of the transistor, and one for the collector, and it shorts away from the load to activate the base. Its resistance actuated, not voltage.

    How to make an opamp out of transistors?

    So, an op-amp will convert a sine wave into a square wave. But if u don't have an op-amp, you can build an op-amp out of transistors instead. Would someone like to draw this little circuit out for me? It would be fun for me to see someone to show me their version of it. Here is radiofun...
