Yamaha M-80 in good physical condition, functionally fully working. This been fully tested, bias is good, no DC offset issues. This is a later model that has all the Yamaha mods (Technical Bulletin 66H) that made the unit more reliable. With the Yamaha updates, this essentially is identical to the M-85 electronically and functionally. Some lettering in the front panel looks erased due to cleaning agent. Its a small area missing 4 and 8 signs over the buttons, hardly very noticeable unless you look for it. New lamps installed, Cold solder joints reflowedAmp ready for another few decades. The dreaded corrosive glue issue with these units has been addressed and mitigated. I replaced Diodes/ capacitors/ resistors to mitigate the corrosive glue issue with these amplifiers. This is a CRITICAL service otherwise your amplifier can suddenly die. over the years the glue eats away at copper and kills diodes/ caps/ resistors depending where it was applied. These M-80s sound amazing, and is now fully functional. The output stages and main capacitors are all good and stock, as are the drivers. I tested full power into 4 ohms and prior to clipping gave me more than 547 watts into 4 ohms (both channels driven). At 8 ohms, it pumps out 287 watts before clipping. Sounds amazing, soft, delicate, detailed. All knobs/ switched were serviced and work great. Please see photos for condition and ask questions before buying if unsure.

This is not your garden variety M-85. It has had 3-4 days of work done on it and has a price to match. It is good physical condition, functionally fully working. This been fully tested, bias is good, no DC offset issues. Works as per spec and better read below. Reconditioned:New lamps installed, Cold solder joints reflowedCorrosive glue mitigatedOld small capacitors replaced with Audiophile grade replacementsDead lamps replaced with long life LEDsAmp ready for another few decades.Upgraded:This unit was rebuilt to have 2x the number of outputs for better damping, speaker control, reliability and current delivery before it sounds constricted. I used the K-amps modules I developed for these M series class A Yamahas. Each output was hand selected and gain matched (a time consuming task). The specs are better than the oem.The speaker posts on these units cannot handle banana jacks or Spades and the user is forced to use bare wire. I broke those off and installed new 5 way binding posts that will accept any cable connection commonly used.Lastly I tuned the feedback profile for a warmer more detailed sonic signature. This requires me to rebuild the output stage which I did when i installed the K-amps dual-pak modules. This amplifier will sound warmer, more palpable and less metallic than any Yamaha out there. I have taken this amplifier to local high end Audio store and know the owner who is a musician, and it raises eyebrows. Its that good. I asked him whats the one thing he would change... and he said can you put an IEC AC socket? Apart from that it sounds great! The dreaded corrosive glue issue with these units has been addressed and mitigated. I replacedDiodes/ capacitors/ resistors to mitigate the corrosive glue issue with these amplifiers. This is a CRITICAL service otherwise your amplifier can suddenly die. over the years the glue eats away at copper and kills diodes/ caps/ resistors depending where it was applied.

Sounds amazing, soft, delicate, detailed. All knobs/ switched were serviced and work great. Please see photos for condition and ask questions before buying if unsure.

Yamaha M85 Amplifier The Yamaha M-85 is a high-end stereo power amplifier, launched in 1986, which outperformed its predecessors, the M-65 and M-45, in terms of power and distortion. Here are its key features: Power Output: 250 watts per channel into 8 ohms, with a mere 0.003% THD (Total Harmonic Distortion), making it extremely clean and powerful.Auto Class A Power: Allows the amplifier to operate in Class A mode, providing a warm and detailed sound, or switch to Class AB mode for increased efficiency and power.Zero Distortion Rule: Yamaha’s proprietary technology ensures minimal distortion, resulting in a more accurate and engaging sound reproduction.Multi-Channel Capability: Can drive up to three speaker pairs independently, simultaneously, or in any combination of two.Heavy-Duty Speaker Terminals: Designed for reliable and secure connections to speakers.LED Peak Power Level Meters: Provide a visual indication of the amplifier’s power output, allowing for precise monitoring and adjustments.Meter Display Load Selector: Enables the user to select the optimal load impedance for the connected speakers.Full Overload Protection Circuitry: Safeguards the amplifier against damage from excessive power demands or speaker mismatches.The Yamaha M-85 is a rare powerhouse amplifier, ideal for audiophiles seeking a high-performance, versatile, and reliable component for their home stereo systems. Its combination of power, low distortion, and advanced features makes it a sought-after component among audio enthusiasts. Unit is used and in need of a rebuild. It powers on and does work but the balance knobs are finicky and it cuts out a speaker from time to time. Im sure its all original, apparently the old glue becomes corrosive and conductive so should be removed. I have a matching C-85 Pre AMP unit for sale too, check my listings.On 17-Jan-25 at 15:41:02 EST, seller added the following information: Amplifier does have a cover for it, just forgot to add a photo with it. Decent shape.

The Yamaha M-85 Stereo Power Amplifier is a rare model known for its high-quality audio performance. With the Yamaha brand reputation behind it, this power amplifier is designed to deliver exceptional sound for home audio systems. The M-85 model is specifically built to enhance the sound output of audio devices, making it a sought-after choice for audiophiles and music enthusiasts. Its power and precision make it a valuable addition to any home entertainment setup.

Up for sale is a Yamaha Natural Sound M85 power amp in good, working condition condition The M-85 amps were very well regarded for their build quality, distinct red stacking meters and the fantastic sound quality. It has Class A circuitry which provides one of the cleanest power sources that’ll allow you to easily drive Snells, Mangepanz and Kappas and other “hard to drive” speakers with ease. It has a few small scuffs and scratches but overall it looks great on the shelf and those large, digital red meters are a real treat. I’ve cleaned the speaker selector switches, output pots and ohm selector switches with Deoxit/Fader Lube but every else is 100% original & untouched Due to the black finish, dust is very noticeable and makes it difficult to take a very clear picture, especially in direct sunlight. The face does have some small scratches but once out of direct light the faceplate finish looks even and all of those blemishes vanish. You can see it in the first picture from the left side vs right side As long as I’ve owned the amp, I’ve never had any problems with it but the ohm selector switches can sometimes fail to latch on the first try when pushed. They might take 3-4 pushes and they’ll latch but it’s just something I’ve noticed. I’ve looked at them internally and there’s no broken parts so it could just be a faulty switch design, weak spring, etc. Perreaux Model 1130 amps had a similar issue with a faulty switch so it does happen. Unless you plan on swapping out your speakers on a semi frequent basis, this will never be a problem or issue. They’ve never not latched but I couldn’t sell the amp without letting potential buyers know.
