Power FETs have been used in a number of Japanese audio amplifiers for some time now , and indeed were discussed in Elektor No. 14, June 1976, p. 628. Readers are referred to this article for a full discussion of the application of power FETs in audio amplifiers. Using power V-FETs manufactured by Siliconix it is now possible to present a FET audio amplifier design suitable for h0me construction, which is based on a Siliconix application note. The advantages , offered by V-FETs in audio output stages are considerable.
