One of the many applications of the Universal Buffer is as the output stage in a preamplifier

In addition to the internal fuse

Modulus-286 Preamp the arc will cause theThe Modulus 286 is a 125 W, Class AB, LM3886 based power amplifier with error correction provided by an LM4562 precision opamp. It delivers clear, precise, and fatigue free sound; and distortion below 1 ppm even at full power. This third revision of the Modulus 286 features improved performance, in part due to the further optimized PCB layout. Modulus 286 Rev. 3. 0 is slightly smaller than its predecessor, but shares the same mounting hole locations,
