Amplifier circuits with transistors 2SC1815

Monday, July 26th, 2010

Generally in work learning of transistor. We can divide work period of transistor be 3 the period. For example period cut off be transistor stop work at this period have no bass current (lb) and collector current (lc) the period is full be intermittently at current flow through with full speed ahead until reach the [...]

High volt mini Amplifier with UJT transistor

Tuesday, September 15th, 2009

This be power amplifier circuit it work with high volt power supply about 125V directly. It composes UJT transistor and transistor the ordinary. This circuit uses transformer sing bail with then apply to high volt and use a loudspeaker has easy. It then get into trouble a little. You can fine to decorate the popularity [...]

2-TRANSISTOR AUDIO AMPLIFIER by BC108

Monday, January 21st, 2008

A simple two-stage amplifier. Use any general-purpose NPN with high gain. It will drive low impedance headphones directly. A speaker will probably require further boost. An old HAM handbook I found in the school library many years ago.
