Tread very warily buying Linn-anything from the last 20 years or so - at some point they changed from linear PSUs to switchmode. Great for efficiency, but many of them have proven unreliable, and not infrequently die irreparably. The older ones can neither be repaired nor replaced since Linn don't keep stock of spares for the older designs. Even when you can get spares, Linn are notoriously expensive.
You'd do well to do plenty of research on hifi forums like Pink Fish to get a clearer idea of which models it would be wiser to avoid.
I am from the era when every 17 year old wanted a set of Matsui 'shoe box' speakers fitted to the parcel shelf of their Ford Escort/Fiesta as soon as they passed their driving test (closely followed by a set of crappy spotlights/fog lights fitted to the front somewhere). And every Currys was rammed full with dreadful cheap 'hifi's' with flashing light graphic equalisers.
Its funny how things change though, as I think I was around 20 YO when I first discovered a Rosewood Linn LP12.
Matsui/Amstrad etc never quite seemed the same after that.
I clocked a NAIM pre-amp on facebook https://www.facebook.com/groups/1802995063348056
That had been serviced recently.
