1) The part C2 at "A" is a 10 microfarad Cap, but I'm not familiar with this symbol. Is it for a electrolytic cap? If so, is it polarity sensitive and what is the polarity, the thick side positive or no polarity?

2) What value does "8K2" represent for the resistor at "B"? I've seen this notation a few times before, but I'm not familiar with it. Does the "K" take the place of the decimal point to avoid confusion? I.E. It is 8.2K as opposed to 82K

3) At "C", is the value 100

*nanofarads*(or .1 microfarad)?
