I've a pair of Linn Kans (020183/4, Mk 1s I think) which I bought new in the 80s. I gave up using them because I could hear a buzz when playing bass notes on one of the pair. The cases were already tatty having been moved too many times and I assumed a repair would be extortionate. I got them out of the cupboard the other day as I was thinking I should dump them and connected them up. I'd forgotten how good these can sound for the type of music I love - acoustic instruments, female vocals sounded so much better than the Mordaunt Shorts I'd bought as a hasty replacement. But that buzz was still there. I was thinking maybe I could get them fixed or attempt a repair myself when I read a suggestion on another forum to see if upending the speaker fixed it. So I tried that and the buzz was gone! Great, so now I'm thinking what to do next. Should I still try to get a repair or just leave it like that upended? Speakers aren't meant to be upside down I guess and maybe this will cause further problems if left. Any suggestions?
