    Running a transistor at a lower voltage (usually called Vcc on schematics) without changing the values of its resistors will tend to cause it to operate more towards cutoff (less collector current flowing). Plus, as was mentioned before, you will have less "headroom" in the voltage swings and it will distort more quickly than when operating at a higher Vcc voltage. Try reading here for some more basic info: http://www.williamson-labs.com/480_xtor.htm#bias-amp

      Oh I remember this guy....

      Asks a million questions, and never likes or understands the answers...

      Even I know an under biased transistor will clip sooner...

      It would be possible to describe everything scientifically, but it would make no sense; it would be without meaning, as if you described a Beethoven symphony as a variation of wave pressure. — Albert Einstein

        I guess this one was underbiased too.

          Just before they burned out, what was the effect?

          Would silicon have burned out faster than germanium?

          More on the differences is what I'm looking for.

          ...Try as I might, I can't quite get the idiom right. The man is an artist, you have to admit.
