noniverting transistor amp

[Stewart Pye]

Hi,

Why not use a comparator. Single supply op amp 15V with, say 4V on the
inverting input, and connect your 5V signal to the non inverting input.
This should give about 13V on the output that could be limited with a zener
to 12V ( or use a voltage divider ), Is it for a roland gate trigger?? if
so it should handle 13V no problem. Op Amps are cheap and easy for this
kind of thing. ( IMO )
