Cool JFET bias trick

[Ethan]

I was playing around with multisim and thinking about Transmorfix relay driver that uses a charge cap to drive a latching relay in the opposite direction. And I thought wouldn't it be nice if I could use a charge cap to supply the -Vgs(off) voltage to a jfet mute/switch application. This way I wouldn't have to mess with bias resistors and could have a simple, cheap mute switch. So here it is.

Looks right clever.
