The Toshibas aren't laterals though.
ECX10N20 Plastic Lateral MOSFET
The ECX10N20 is a suitable replacement, substitute or equivalent for the 2SK1058.
The Renesas 2SK1058/2SJ162 are lateral so are the EXC10N20/10P20.I was asking about the Renesas 2SK1058/2SJ162? If it's easier to use laterals, then I'll go for EXC10N20/10P20. I don't want to mess with temp tracking bias circuit. I want to KISS. Any time I built a SS amp I end up blowing up a few sets before I get the bias set correctly, due to thermal run-away.
