Download Java Virtual Machine Advanced amplifier calculator Main mechanical television page HOME Camera experiments page Return to Top	Now with industry standard resistor & capacitor values! Have a 56K or slower modem? Please allow 1 minute for calculator to load. See footer for important disclaimer. Also note: With some transistors, you might need to adjust the values of Rb1 or Rb2 slightly for correct bias. Transistor type: I suggest type 2N2222, 2N3904 or 2N4401 (or equivalent) devices. (Device hFE = 200.)
