Hello Ive had a u87 for years, it gradually became noisy and crackled and switched off with close vocal work even with a pop screen, I decided to clean the capsule myself using method described by Neumann using distilled water and soft brush. There was a huge improvement on unwanted noise, crackles, pops etc. They have all gone away. The switches operate very smoothly and quietly. I gave the U87 a breath test without pop screen to see what would happen. This test was taken very close to the capsule and it did indeed cut out and return to normal within a few seconds without noise, just off then on again. Is this the best I can expect to get it? Is it possible to get a capsule to not go silent for a few seconds when its fogged with breath? I haven't a new U87 to make a comparison, so can you tell me please, would a new U87 keep working under such conditions with a fogged capsule? If it would, then I can conclude that my cleaning job was a success. Can you help please?
