New LM3886TF 68W amp chips hifi grade free post LM3886
***NOTE: I keep re-listing these chips and there are always loads of watchers at the end, (15 at the moment). Email me with what you want and I'll do a great deal: andy.****@btinternet.com At this rate, I'll sell them all sometime in 2025. Go on, life's too bloomin' short :) ***
LM3886TF Hi-Power Audio Amplifier ICs. National Semiconductor ( 10 PER PAIR).
These chips are genuine and unused. They are stored and handled with all Anti-Static precautions.
There are plenty of excellent reviews on the net for this amp and they sell for 6.32 each on CPC, (cheapest place I could find them):

LM3886 Overture Audio Power Amplifier Series High-Performance 68W Audio Power Amplifier w/Mute The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4 load and 38W into 8 with 0.1% THD+N from 20Hz-20kHz. The performance of the LM3886, utilizing its Self Peak Instantaneous Temperature ( Ke) (SPiKe ) protection circuitry, puts it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Operating Area (SOA). SPiKe protection means that these parts are completely safeguarded at the output against overvoltage, undervoltage, overloads, including shorts to the supplies, thermal runaway, and instantaneous temperature peaks. The LM3886 maintains an excellent signal-to-noise ratio of greater than 92dB with a typical low noise floor of 2.0 V. It exhibits extremely low THD+N values of 0.03% at the rated output into the rated load over the audio spectrum, and provides excellent linearity with an IMD (SMPTE) typical rating of 0.004%. Examples of applications include component stereos, compact stereos, self-powered speakers, surround-sound amplifiers, high-end stereo TVs, etc.
