• Desiging the amplifier stage: first attempts always fail

    The circuit is going pretty well so far. The problem I'm having is with the transistor amplifiers.

    When I first attempted the first stage of the amplifier, I ended up producing a rather nice and smoky aroma—like there was a component barbeque somewhere. I ended up frying one of the coupling capacitors, so that was great.

    I've decided to go with a common-emitter amp because, well, who doesn't use those?

    Anywho, I need to get back to finishing the design for the first stage. I'm planning on having variable gain for it and the second stage, but I think I will incorporate potentiometers into them later.
