Power amp 100W with V-MosFet
Monday, June 8th, 2009

One still designing that it uses in the exit transistor of technology V-mosfet. This transistors to us offer a lot of virtues concerning the simple bipolar transistors, as high speeds, thermic stability, low distortion etc. Beyond this circuit use also other useful solutions as use fet as source of current [ Q3 ], trimmer TR1 [...]

Bipolar Amplifier HIFI OCL 100W by BD317-BD318
Friday, May 22nd, 2009

If friend want Bipolar Transistor power Amplifier Circuit. , In model HIFI OCL 100W RMS. I sizes think this circuit may is the one choice interesting , use Transistor the important be BD317 and BD318 unless have transistor number BD139,BD140,BC556 then seek buy easy , when see power supply use voltage source 35V just then [...]

100W HiFi MOSFET Amplifier using 2SK1058+2SJ162
Saturday, November 22nd, 2008

The neat thing about the series 5000 is that it was built around new (at the time) Hitachi lateral power MOSFETs. Most power MOSFETs (VMOS, trenchFETs, HexFETs etc) use a vertical structure, where the current flows vertically. This has the advantage of stunningly low Rds and hence high efficiency, but does nothing for linearity or [...]
