Is it k67 or k87? I hope you measured the capacitance between the two backplates before separating them. Presuming they are electrically insulated. Microns in diferences of the spacing can mess with the performance considerably. Yes there is a spacer there, but overtighting or undertighting will still affect the distance. Not to mention you have to take care nothing gets on the spacers, or backplates. Dust, hair, buggers, i've seen much crap getting stuck there.I tried grounding both the backplate and diaphragm to discharge any static. No change. I left it sitting open on my workbench, with the diaphragm facing down, to let the moisture (from blowing on it) dissipate. I went to put it away and a lot of the marks are gone! It still measure poor, but 160pF vs the 500pF that is had been.
I'm not expecting this thing to return to normal, but I'm gonna give it some more time and see what it does.
@k brown, you may be right about the mylar. Could it possibly be the gold that was holding shape? Maybe the Mylar is taking its shape back.
Definitely the plan!Hey, that's great news! To be "on the safe side", perhaps the affected side should be reinstalled as the "rear" (less frequently used), and the unaffected one used as the "front"?
I think it's a K67. I believe the spacer between the backplates is conductive. Pretty sure the backplate terminal was terminated to one backplate with a single screw.Is it k67 or k87?

Something like that. I was using compressed air to get lint off the capsule, and in a moment of complete inattention, I swung the canister around behind the capsule, which positioned the jet at 90 degrees, rather than the usual approximately 170 degrees. It was all over in a millisecond... OK, lesson learned.. . . forgot the bloody pop screen!
i use the type of brush they use to clean antique gold leaf for this. usually white goat hair. you can find them from museum equipment suppliersI was using compressed air to get lint off the capsule
How do you clean it? Alcohol? Water? Another goat?i use the type of brush they use to clean antique gold leaf for this. usually white goat hair. you can find them from museum equipment suppliers
This capsule actually has two tiny plastic rods that sit in holes to line them up.I havent pulled a working LDC appart , but one thing struck me , it probably makes sense to mark the alignment of both the backplates and their respective membranes, spacers before you go at it . So everything goes back to exactly as is left the factory .
I don't, generally. If it needs cleaning that isn't just dusting, it's covered with salt or oil, and that's complicated. The capsule hopefully doesn't get to this state, but it depends on usage. Worst capsule I ever got on the bench came from some dude who smoked weed so often that it was caked in weed oil that had deposited as droplets from his mouth over the years. It was multiple times thicker than the membrane. Unbelievable.How do you clean it? Alcohol? Water? Another goat?
Ack! That's disgusting. Buy him a pop filter and a toothbrush.I don't, generally. If it needs cleaning that isn't just dusting, it's covered with salt or oil, and that's complicated.

natural hairs are best cleaned with only water i think. you really don't want to strip them of their protective layers. if it's stubborn, try a baby shampooAck! That's disgusting. Buy him a pop filter and a toothbrush.
My post wasn't clear, I meant cleaning the brush. I don't clean capsules with water, I just lightly brush off the dust if it's starting to accumulate. Figured buying a better brush would be smart, but I want to clean it after use.

the capsule itself smelled so strongly of weed that i had to keep the backplates in a plastic bagEEee-yuk.
Hmmm ... are you sure it was actually weed oil, and not polyunsaturated cooking oil from all the munchies he must have consumed after smoking . . . ? That might require a different "tack"? Anonymous
so rude after he went through the effort of conformal coating it for you over all those years.............Once upon a time, I was going to purchase a Studer mixer from a guy so I went to see it at his house. He had smoked so much weed that not only were the outer mixing surfaces coated in resin, but the inner circuit boards too. I didn't think I could ever clean it well enough, and so passed on it. His weed smoking was a terrible thing to do to such a fine piece of gear.
Perhaps that would be called 'non-conformal' coating.so rude after he went through the effort of conformal coating it for you over all those years.............
