Not necessarily true, but if you buy any piece of vintage equipment, you should have it thoroughly checked by a qualified technician which can add several hundred dollars to your ownership costs.
Lots of knobs might cause more repair chance
Pre-amplifier like Accuphase, they have many functions and according to the opinion of my hi-fi friend, he said, the more knobs on the equip. , there will be more chance of repair.......... Is it true? I am thinking about purchase of Accuphase C-290 which is around 22 years old from it's launched date, do you think it is still a good gear for using such kind of old hi-fi?
