Good Power Amplifier is not so easy to build.
Preamp is much easier.
For example use only one dual op amp.
But that is not very romantic, is it?
Building a transistor preamp should not be difficult.
Here I show one way.
Symmetrical input using LS Dual JFETs.
Complementary ZETEX MOSFET ouput stage.
Result gives fairly low distortion.
Like THD 0.001%
Building is easy using the few small transistors.
Even easier if you already have +/-12V or +/-15VDC supply.
Of course the supply should be regulated.
