Class A 18W Amplifier
Single ended 18W with current sources and op-amp in the first stage.
Class A sound, I would like to be able to test different opamps but do you know
a good opamp that can output +/- 17V other than NE5534 ?
Q5,Q6,Q2 transistors on large heatsink.
Dual voltage: +/- 20 V supply regulated, +/- 24 V unregulated
Result almost 32Volt p-p at 24Khz , 8 Ohm load
