I have a Yamaha M-80 Stereo Power Amplifier for parts due to its recent protection light on issue. It was totally rebuilt by Legendary Amp 8-9 years ago (http://legendaryamps.com/restoration.html). It has been working flawlessly until recently I experimented some spade-terminated speaker cables and somehow caused the protection light on. Right now, it is not generating any sound.This is a legendary amp that went through the full restoration, which could be a great project for who are electronically savvy for this clean-sounding amp boasting 250 watt per channel under 8 ohms. Per the insights from the restoration company, the M-80 offers massive output power with extreme reproduction purity for the discriminating audiophile who demands the highest possible performance in an audio system. The M-80 delivers 250 watts of power per channel into an 8 ohm load with a mere 0.003% THD, a steller damping factor of 250, more than enough power for even the most demanding listening requirements. Whats more, Auto Class A Power with Zero Distortion Rule amplification makes the M-80 one of the cleanest, tightest amplifiers youve ever heard. As benefitting an amp of this class, the M-80 supplies substantially high output power on sudden demand, and drives even a low-impedance 2-ohm load for full compatibility with virtually any speaker system. Wide range LED peak power level meters and full overload protection circuitry are also included. Overall, the M-80 is an outstanding accomplishment in power amplifier design, not only in technology but more importantly, in natural sound reproduction quality.Please let me know if you have questions. Thanks for watching. No spammers please.
