Hello folks.  I just bought a used 4B off someone because I always wanted one but couldn't afford a new one.  Anyway, its over 20 yrs old - so no warranty remaining.  

Now this thing is not turning on.  Any idea what could be wrong here?  Could it be as simple as a power switch?  Are there some common problems with this amp that show up over time due to normal wear n tear?

Thanks for your help!  And by the way, hello from a newbie.

Cheers

Edit:  Out of curiosity, does anyone know how much Bryston charges for servicing these things?

I would start with simple things like checking the fuse and power connections.  There should be a downloadable manual from Bryston website for fuse specifications.  www.bryston.ca
