This biestable vox circuit was found in an old documentation. The circuit makes use of components of the time (80's) and can work as a shield since the power is 5 V.
This high-voltage regulator uses only two components. The resistor is a wound wire type with 1 W...
The circuit shown makes use of a symmetrical 15 V source and an LM3900 transconductance...
We can either supply this circuit with 12 V if we use a relay for this voltage as well as 6 V if...
