I'm trying to figure out where the diaphragm is on these caps. Is it right behind the screen behind the bars at the very front of the cap? I was just examining them and it appears that the screen might be pushed in on one side, so if the diaphragm is right behind it, it isn't perpendicular to the body of the mic like it should be. I'd take a picture, but I don't think it would show well. I haven't had a chance to run these live, but have tested them by recording from computer speakers. I don't hear much difference between them and there isn't a hum, so I wonder if it is worth sending if off for repair? If it is messed up, any idea if it is possible for AKG to fix this and how much it would cost?

shine a light in there and you should be able to compare the 2. Make a test run and see what the levels are then switch cap and rerun test...if one cap is slightly less in response, you may have to either match up your cap/bodies/pre/cables (or just turn one side up)....to get each to be close OR if it is was off send it to AKG for review.

Thanks JAH. I had pretty much done everything you suggested already. Here's the recording I made with the mic 1' away from my computer speaker. Only change was taking off and putting on caps. File was roughly chopped up in SF5 and peiced together then encoded to flac. It's about 5 MB - if anyone wants to give their opinion on differences and guess which cap is dinged I'd appreciate it. These are ck63 caps btw.

wish I could help more but Firewall at work and limited to dial up at home (in the boonies, shit cable doesn't run here...wtf)...someone should be able to chime in. How much diff is there btw caps in dB...under 2, I wouldn't worry about it if all responses are ok and you have the ability to make up for it in the chain. Otherwise looks like a new cap for you. ;-(
hope it works out

I would guess that the 2nd example of each song is with the dinged cap

Thanks for listening - I sent you a PM to tell you if you're right. Don't want to spoil the surprise for anyone else :D

soooo... you got a back ck63 cap in that transaction???!?!?!?

Yeah looks like one of the caps has a dent in the top/front screen. Doesn't seem to have a drastic effect on the sound quality, but I'd like to know if it's going to throw off my included angle when running ORTF, DIN, etc. Did you listen to the two recordings?

i havent yet, il check em out now
i had a ck61 cap that was ever so slightly dented, i mean barely. and it didnt affect anything
-
Here's a photo - I emailed AKG about repair, but haven't heard anything.

My concern is that the diaphragm on the damaged mic might be pointing towards the good mic instead of straight up like it is supposed to.
-
AKG response was that if it touched the diaphragm it would already sound bad. If I wanted to do things the cheap way, I should use it until it sounds bad and then send it in for repairs. Repair would be $80 + S&H. ::)
-
So...how'd it happen?
-
Bought some 460s, 61s, 63s and RA adapters from a guy off Ebay. Everything was sold as "excellent condition". ::) I tried them out and everything sounded good so I gave him good feedback and forgot about it. I've been busy since then and haven't really looked at them until yesterday when I noticed this. It's pretty easy to miss since the outer part doesn't have any marks really.
-
wow. that is 10x worse than mine was dented
i just had a small tiny dent in the black outside rail looking things...
i guess i didnt really have a dented cap, just the outside was dented and didnt affect performance
i dont see how they would have done that w/out damaging the outside of the cap??!?!?!?!?
-
you mean you need that small thin layer of mesh screen ???
mine dont have anything over either cap, you can see the screw-like structure inside :P
-
Bean could you get a hold of a camera and take some shots? I would really like to see what's under that screen. You don't need it, but it might be good to have it. Do you have screens under the side vents? The service guy in Nashville (I think there may only be one) doesn't charge too much, so if you wanted some screens put in, I think it would under $60 for both, but you could call and get an estimate. I also found out that the screw on the body that needs to be tightened to avoid the ground hum some people get is actually not supposed to do that job. There is a tiny (1/4") spring that often gets lost when people unscrew that screw. The spring is the only piece that actually grounds anything normally. He also replaces those springs cheap. Random AKG trivia of the day.
-
out of curiosity, what color is the plastic inside the caps? do they unscrew easily or not so easy? i ask b/c akg changed how they make the ck6x caps. i have one that is about 5+ years old and the very front of the cap doesn't extend out and the inside plastic is clear. the other cap had a grounding issue so i got a brand new one. the inside plastic is white, there is more of it, and the front of the cap sticks out a tad instead of being depressed "in" or flat like the older cap. the cardiod logo is also larger on the new cap....i just found this all amusing.
-
sorry jon, i was just being an ass about the no screen thing :P
and your totally right about that lil screw, i would have random times when id plug my xlrs into my mics, then into the dmic, and i would get a VERY loud, audible grounding hum, keep that screw tight and you wont run into those dreadful problems
luckily, i caught them before i actually recorded or id have some WHACKED recordings, and FWIW, it took them years to get loose like that
-
Oh yeah er em cough cough uh I knew that :P
Jon - both 63 caps are clear inside by the gold pin. I have one 61 cap that is clear and another that is white.
I decided to run them at moe on Saturday and I liked the result, so I don't think I'm going to sweat it - looks like it's just cosmetic. Thanks for all the replies. +Ts

I had a drunken moment and dropped one of my oktavas and i have a good size dent in one of the caps but luckly dont have any advers affects frome the fall or dent.
