Joerg...

I'm about to do my first FET audio gate. Heretofore (for the last 30 years)
I've been relying on an opamp output at some positive voltage, a decently
high value resistor off the output (say, 100K or so), then a bipolar shunt
to ground, then another decently high value resistor to a summing junction.
I'd like to reduce the package count and not have an opamp (or it's cheap
cousin the cmos ibuffer with a feedback resistor) for each audio channel.

I'm leaning towards initial testing with a 2N7000 ... cheap, readily
available, predictable Vgs turnon voltage, and all the rest of it.

Comments?
