Mr  Tanner:
 I just picked up a Bryston 4B SN: 414720. Can you give me some idea of the age?
 I grabbed it from the first owner for a really good price.Trouble is,he's not sure when he bought it.He claims he only used it for about 3 years,and then just put it away. At first,I was skeptical,but now it looks as if he may have been telling the truth after all.It's in almost brand-new condition!
 I'm letting it warm up with my Maggies'(MMG's) as we speak. 

 Regards,
Patrick
