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?

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.

Your friend has a point, but in my opinion its not that big of a deal. Knobs (Pots) have a tendency to wear and/or get dirty. When this happens, you'll hear a crunching type of static noise. In most cases, the pots can be cleaned and the problem will go away. Sometimes they need to be replaced.

There are other issues you can have with older equipment, but I think your friend was talking about the pots specifically.

I don't think, I just know it's good gear and will always be good to use and will always be worth to service and it has published service manuals with schematics.
If you go for newer components, they mostly compromise in built quality, functionality and no service manuals or schematics. Instead of going to local tech around the corner, you will have to send it to 'authorized' repair facilities or factory and once such factory release a new model your old model will be forgotten and so is the money you've spend will turn to a few bucks.
Stick to this unit as it will never loose value. After all, it's not too many knobs compared to other vintage units.

Thanks for your kind reply.  The problem is the source of the 2nd hand Amplifier. Most of them were not sold by the formal distributor, so it is impossible to get after service from the authorized technicians served in the distributor.   Also, the old equip. might run out of parts either, that means you might unable to get is fixed.  Even though some good old gear were using good quality parts, but after 20 years or more usage, there is higher possibility of repair requirement.  You have no way but to find the service engineer around the  corner.
