I thought the beryllium tweeters were coated to protect against corrosion or, like everything else, nothing lasts forever?
Fascinating stuff Vint Age. Thank you for the copy promo stuff. Those were the days when, you could manufacture anything without a care for our planet. I thankfully, have two pairs of NS1000's. First pair bought 1982. They were powered by my lovely sounding but, underpowered Meridian 101/105 set up. The consequence was that I must have blown at least half a dozen tweeters and a couple of mids. Looking back, I can't believe that I just threw them away. I reckon I cleaned out the last of Yamaha UK stock. I was so relieved to find that Manfred Stein of QUAD MUSIKWIEDERGABE in Germany could re-coil them. Can't find anyone in the UK. He's done quite a few of mine.
My second pair NS1000, bought 2002, is powered by my B-2, of course! Which, is still going strong after Audio Clinique and my own work.
Now, a question. Can anyone recommend a better alternative to the C-2, please?
