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 [...]
