This is a very low hour unit from the original non-smoking owner. All the original lamps were good but I went ahead and replaced the 3 meter ones just for longevity. The only two capacitors I replaced were the ones on the input if the signal path….I used Wima films for better signal passing (sound quality). I properly cleaned/lubed the controls, set idle current and DC offset (less than 1 mv DC per channel). I lubed all the tuner string pulleys and knob bearing for a smooth time. Lastly, I used new heatsink past on all the output transistors. This Yamaha performs as it should and sounds fantastic….Free shipping!!!!
