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.
