LM1875 AMPLIFIER 2 x 20 watts.
This subwoofer amplifier circuit consists of a TL072 low-noise JFET dual operational amplifier (IC1) and two LM1875 (IC2 and IC3) power amplifiers. Circuit operation In stereo mode, each half of the TL072 operates as a non-inverting input amplifier, with a gain of about 2.8 times as determined by feedback resistors R5 and R6.

LM1875 Datasheet 25W HIFi audio amplifier circuit
The LM1875 ("eighteen-seventy-five") is a monster of a chip in a very unassuming package, and another much-loved chip in the DIY audio community. The official datasheet (PDF) claims the ability to drive 20W into 8Ω loads given +-25V, and up to 30W supplied with an extra +-5V of juice. and all at less than 1% THD.

LM1875 Based Simple Amplifier Full Project Available
Understanding the LM1875. This amp is in fact a power opamp with open loop frequency of 70hz and 90db gain. This is measured with 2k load. If the output is a tranconductance amplifier as I can guess from the internal circuit, than the OLG/BW depend upon the load. This is not specified but what betrays is the need of output snubber to limit the.
