The Yamaha M-80 Amplifier came from a local estate and was being used until it was put in storage a few years ago. Since that time it was spent in a climate controlled storage area and is in good condition with no major signs of wear. We did plug the system in to make sure it powered back on. We do combine shipping so please check out our other offerings. If you want to make an offer do it through the listing. We do not answer messages about prices through eBay messages. An unpaid item case will be opened for any item that has not been paid. Gils Online is located in Hamilton, OH.

This is by far the highest quality sound system weve ever owned. It is a vintage Class A Yamaha 2-Piece Amplifier set from the mid 80s. The amount of functions to help modify the sound to your exact needs and preferences is insane! It was the top of the line at the time, and will still put todays gear to shame! All the components inside are top-notch. Even the audio ports on the back of the C-80 are gold plated. Yamaha really went above and beyond when designing this kit. The sound quality is absolutely amazing, and these bad boys can be pushed and deliver outstanding performance. Rich lows, clean highs. This is the kind of kit you will never need to upgrade. Esthetically, the C-80 is near mint, virtually flawless. The M-80 has the top left corner with some scuffs, as well as one near the back and on one side. The face of both are near mint (there may be some dust on the pictures, but we looked them over carefully, and no collector would be disappointed with the condition). Also included are both the user manuals as well as a store brochure of the product line. Shipping these will be quite expensive, with the M-80 alone weighing in at around 50 pounds. It will require a massive amount of packing material and a very large box to accommodate it. Both units will be sent in separate boxes, with full insurance coverage, which also adds quite a bit to the cost of shipping. Shipping is included in the price, but know were planning to spend roughly 500$ in shipping fees and insurance on our end to ensure a safe delivery. Please note that the M-80 does get quite hot and should be on top of the stack to allow proper ventilation, as on the pictures. This is not a flaw. It is just a consequence of how powerful it is, just like other Class A amps. If you have any questions, please contact us prior to purchasing.

Yamaha M-80 Amplifier - Fully Restored For sale is the well regarded M-80 amplifier from the 1980s and well built in Japan. The amplifier has been fully refurbished. The changes/upgrades are listed below. The M-80 has a loyal following because of its high power and trademark Yamaha sound. This amp will drive 99% of the speakers on the market today to reference volume levels. SEE PHOTOS for imperfections that could not be remedied. THIS AMPLIFIER HAS BEEN FULLY TESTED FOR OVER 3 MONTHS WITH NO PROBLEMS. From a period review: The M-80 is an extremely powerful amplifier, differing from most (especially those of Japanese origin) in having ratings for driving loads as low as 2 ohms. Among its special features is a switchable “Auto Class A Power” circuit that is supposed to operate the output transistors in Class A (for minimum distortion) at low power levels and make an imperceptible transition to Class AB as more power is required. Both the M-80 and the C-80 employ what Yamaha calls “Zero Distortion Rule” circuits, apparently a combination of feedback and feedforward techniques that, in theory, can reduce distortion to zero. The M-80 power amplifier, as its weight of over 50 pounds implies, is not an amplifier to be taken lightly. Its top became very hot (above the internal heat sinks) during the one-hour preconditioning and the following high-power tests, but it was no more than moderately warm in normal use. The M-80’s power performance into 8-ohm loads was quite impressive, but the really special qualities of the amplifier became more apparent when we drove lower impedance loads. For example, its dynamic headroom into 4 ohms was no less than 3.78 dB, with short-term power getting up to 787 watts per channel. Finally, we came to the 2-ohm measurement, the nemesis of so many amplifiers. It wasn’t even practical to drive both channels simultaneously into 2-ohm loads, since this overloaded our 15-ampere test-bench power system! Driving one channel, the clipping power was 612 watts, and the dynamic power was a staggering 1045 watts. The amplifier was stable when driving reactive simulated speaker loads and the standard IHF reactive load. Given Yamaha’s emphasis on the low-distortion circuitry of the M-80, we should not have been too surprised at the results of our distortion measurements. They were indeed difficult and time-consuming to make, since the 1,000-Hz THD of this amplifier (driving 8-ohm loads) was less than 0.0025 percent up to the clipping point, and typically well under 0.001 percent. Even with 4-ohm loads the distortion never exceeded 0.01 percent, and with 2-ohm loads it rose from less than 0.001 percent at a few watts to 0.02 percent at 300 watts and 0.15 percent at 400 watts. The replaced parts are also pictured. This amplifier will provide another 40 years of sound performance. The following work has been performed on this unit: Cosmetic: Premium binding posts installed (Speaker C has been disabled) Faceplate and knobs detailed Cleaned inside and out Corrosive bonding glue removed Top and bottom covers have been sandblasted and powder coated. Overall condition is average Service: Electrolytic capacitors completely replaced with Nichicon capacitors Filter capacitors tested and confirmed to be within specifications Upgraded with WIMA film capacitors where possible New speaker relays installed Circuit boards cleaned Wires wrapped and redirected Transformers sealed where foam reacted with top plates Adjustment trimmers replaced with Bourns units Damaged resistors replaced with Vishay military grade units Cold solder joints touched up Idle adjusted Fully tested HIGH OUTUT TESTING FOR 3 MONTHS Packaging will be done to excess.
