NIKKO amplifier ref NA-1090: 33 years working well

Hi,
The first failure I had was in 1986 after 5 years use; had to replace one of the two big capacitors of the power supply.
Also had to replace all front lights some times, but easy to do.
Switching buttons can fail, too, but repair is ok.
I am very happy with this robust amplifier.
