Dear DIY fanatics,
New here, I've got this schematics from school days in the early 90's. Its been long time using this amp at home and planning to upgrade same schematic and power for outdoor use up to 2 ohms.
Original supply was +- 50v . Want to make it +- 75 volts.
DIY experts are invited to join, comment and revise this circuit.

@AN214Q sir if you like try this simple design.this can work up to -/+70vdc rail voltage.just add one more pair output transistor.this can handle 4ohms speaker,with a good heatsink & force cooling
