VSSA FOR HEADPHONE

[bimo]

Hi, all. I just learn how to use LTSPICE and I want to modify VSSA for headphone amplifier.
Here, my schematic diagram. I use +15V,0,-15V power supply and approximately 100mA for quiescent current output transistor. The simulation is good. But I want suggestions from the experts if I miss something here.

1.5W power dissipation for each output power transistor.

Transistors rated for 12.5W @ Tc of 25C
or 1.25W at Ta of 25C

Heat sink is required.

Just in case you forgot.

Thank you, Dug. I will remember it

I have +/- 15V VSSA original 6-transistor circuit running. It puts out 4.8 vrms before clipping.

I think 2sj162 and 2sk1058 lateral mosfet is too much and too expensive for headphone amplifier. I made VSSA with lateral mosfet for my 8 ohm speaker.
