Linn Akurate 242 version?


Over the past 25 years, I've owned a lot of Linn gear.  I've always really loved their speakers and recently acquired a pair of Akurate 242's.  I'm trying to determine is they're a Mk.1 or a Mk.2.  They appear to be later models but is there an easy way to determine based on the serial numbers?  Mine are 957xxx.  Any information is appreciated.  Cheers!

Email the serial number to linn support at helpline@linn.co.uk and they can tell you whether they are mk1 or mk2.
