I'm in the process of restoring my DM7's. the tweeters work ok but are not performing as they should.
I have read on a few sites ( maybe even this one - but I can't find it)..) that carefully applying shellac to the silk dome will restore the sound- is this correct? Any advice on how to apply shellac and how many coats would be gratefully appreciated.
The domes are now available from good hifi in the Netherlands, there's a good 'how to' video on their site, so there is a back up plan..
