enjoyfebruary Posted October 26, 2016 Report Share Posted October 26, 2016 I just received a couple of used COS-11s in the mail and the mesh screens look a little gunked up. I haven't even gotten home to test them yet, but considering that they are working and I am happy with the sound quality and do keep them; does anyone have a preferred method of cleaning some of the gunk out? I do have a can of spray electronics cleaner that would probably take care of it, but maybe someone else has a better method? Thanks!

RPSharman Posted October 27, 2016 Report Share Posted October 27, 2016 If they sound good, then don't mess with it. If they don't sound good, you won't know if it's the "gunk" until you replace the screens. So you're in a bit of a predicament. I'd drop by LSC if you're in LA. Mark can put them in the magic chamber and plot the freq response as compared to a new one. If he thinks the screen needs replacing, you might be able to have it done then and there. You will need to pay for the time, so this isn't a free endeavor. Quote Link to comment Share on other sites More sharing options...
