Mosfet Pair

[LaceSensor]

Hi

I am looking into envelope control of PT2399 or similar.
I have a snazzyfx wowflutter that does this quite well.

The circuit snippet here seems pretty wasteful of a DIP14 chip



Could you replace that with just a MOSFET pair like this?

If I'm reading this correctly, you've got a partial rectifier that's being used to send control voltage to a voltage controlled resistor. You could probably get away with replacing the whole IC with a high gain BJT. you might have to twerk some values to get it to work optimally.

Yeah but can I use the Mosfet pair

[Aleph Null]

Probably?
