This transistor class B 5 W amplifier was found in a 1969 Mullard documentation. The transistors are from that time, and modern equivalents may eventually be used.
I found this circuit in an article in a 2003 publication. The circuit is an example of how to...
This circuit causes an LED to flash at a frequency determined by capacitor C1. The circuit can be...
This multi-purpose power supply provides voltages of +15, -15, 300 and 1 000 V and is very useful on...
