Here you are. A tiny amp which achieves maximum output power 70W/4ohm and 45 into 8 ohm. This module can be used as replacement of some IO amps like LM3886, TDA7293, TDA7294, LM3876....
Technical parameters:

Supply voltage: max. + / - 33V

Output power: max. 70W/4R

Frequency response: 10 to 98 000Hz/-3dB

Harmonic distortion: 0.066% in 70W/1kHz; 0.057% at 70W/10kHz

Intermodulation distortion: 0.24% at 65W / 80 +7 kHz

Input sensitivity: approx. 0.45 V

Current protection: 2x3, 15A fast fuses

Slew rate: 12V/us

Min. impedance: 4R

PCB dimensions: 72x56 mm
