thinking about reviving this circuit seeing how my PCboard etching has improved and have all the parts.
BUT looking at the power supply, trying to figure out WHY it has an op amp for the supply. I recall I got the idea and schematic over at the headwise website but can't find reference to it for reason it was put into the circuit.
The FETs will not be needed.
thinking that with the two 9v batteries I should be able to construct a duel supply?
any input or suggestions
