Skema Rangkaian The 25 Watt MosFet Audio Amplifier re-tested recently after 15 years
Saturday, October 17, 2009
this is 25 Watt MosFet Audio Amplifier page, is by far the most visited of this site, and is on-line since March 1999. The circuit has been built by many 
amateurs all around the world and is still very popular: as a logical consequence, in these years this small amplifier was frequently debated in Audio forums and rumors arose about its quiescent current stability and other topics.

The tests results, with some added comments are shown below.
