So, how do you test the diaphragm tension of an assembled capsule, or do you just listen empirically?

It always seems a little circumspect to me to peg difference down to just that. Small differences in the size of holes in the backplate for instance, etc., could seemingly make as much difference in end frequency response.

It also seems like low tension can be a bad thing... one of the first things to make a capsule sound bad, IMO, is low tension that starts to result in a capsule being overly sensitive to plosives.

U67 reissue: to buy, or not to buy, that's the question!
(I hope to know more after reading the review.)

The discoloration does not look to me to be due to deterioration of the gold sputtering, but due to an uneven sputtering process during manufacture. I would therefore not attribute any sonic anomalies of the mic to it.

The proof of course would be capsule substitution. But from the pictures, the capsule looks super clean.

my friend took me to a studio heís been working at last night to check out their Sony C800G. It had a really weak bass response but no campfire noise or anything that made me think it was the tube so I checked out the capsule and noticed it had a strange discoloration on the top of both sides. I hadnít seen this before so I thought it may have something to do with it. The studio was set up very improperly so we took out every single cable and redid the whole signal chain and honestly it sounded like it was working after all that but I am running off of no sleep so itís hard to really trust my ears after the day I had. I will go back soon and check if itís all good and if not I will get some recordings to post.  But even if it is working iím wondering what would cause this patina on the capsule or if anyone has dealt with this.

Thanks for any info!

Our U67 originally came from Belgium and the transformer is strapped for 200 ohms.  My understanding is that provides 6db more output. I am looking forward to reading Klaus's upcoming review.

I had one in a DIY U47. Way different than an original one, much more open. Quite a nice capsule, but not a K47. Heiserman himself said on a forum it was not a sonic clone, more of a personnal take on it.

Does anyone around here have any experience with the Heiserman HK-47 capsule?  More expensive than the Chinese capsules ( of which Oliver Archut was reasonably complimentary), but much less than the real McCoy.

Dear Klaus,
Your diagnosis was the right one! The AC701 is well the culprit. I finally decided to replace the tube and everything is back to normal. In addition, since I had previously replaced all capacitors and some resistors that could be the cause of this instability, the combination of the new tube and these new components give an excellent signal/noise ratio. Thank you, thank you very much!
Mike

Of course, with close-ups!
