You can use them in three pattern mics, the figure eight will just not be perfectly mathematically even

I went ahead and ordered the normal ones. Just so I can tell my friends with a straight face that these mics have all the math.
Ari, I apologize too!
I was also getting confused.
I am not a native English speaker, I use an online translator. In my native language "under" is translated "below", "one paragraph below" so it was understood that there are three categories:
Normal
Cardioid/Omni
B-stock
But there were only 2 choices.
Now I understand.
Thank you very much!

Cariod/Omni = B-stock
Yes, I got it. I was starting to think that maybe the graphics display on my smartphone had a bug, but Ari's explanations cleared up everything.
Thank you both!

sorry but is your tab counter smiling
Yes, and no.
Disregard this post if this was already brought up - i admit to not reading the entire 100+pages.
If you sell B-Stock at a reduced price (wich i love!) think about marking them, to prevent them beeing sold years later down the line as "perfect" and people complaining. As you have serial numbers on your capsules maybe a small online tool for people to look the number up, as with "sell-date" and "b or a stock"
just my 2cp.

Hi Everyone, this is my first post here after lurking from time to time in the past. I just received 2 matched flat k47 capsules from Ari, and they are beautiful. I bought 2 turnstile audio tac1100 mics to put these in, and I replaced the capsule in one of them. However, I’m only getting figure 8. Cardioid and Omni are very very faint.
The capsule that is in the mic originally has a wire on the front and back diaphragm, as well as one wire on the ring on the backside, so from pictures I have seen it is a 67 or 87 style capsule? I soldered the k47 wires to the same spots to which they were connected previously, but something isn’t right. I am 99.99999999% sure that this is user error; I don’t think the capsule is the issue from everything I’ve read about Ari’s quality control and from the email interactions that we had.
I’ve done a lot of searching to see if there is any general info on this issue, but nothing comes up except something I remember reading about “then you’d wind up with a figure 8 only mic,” however I can’t find where that was written again. Is there something easy that I should check for? I can post pictures if that will help.
I am not an electronics genius (obviously) but I can solder and troubleshoot. One project I did years ago was the royer MXL tube mic mod. I originally had a weak sound from it, and David Royer answered my phone call and he let me know that I had the older instructions with the newer circuit board, so I had soldered the ground to a mounting hole. When I soldered it to the correct place (opposite the instructions!) it was glorious. So, I’m hoping there is something simple like that in this case.
For the record, the figure 8 compared to the other mic with the stock capsule’s figure 8 is so much better. So much better as in not even close- much fuller sound without the pinched top end of the stock capsule. Not that the stock capsule sounds bad, it just sounds typical of the inexpensive Chinese factory mics.
Thanks so much in advance for your help. I’m going to try wires in different spots to see what happens, but any insights are welcomed. These are the turnstile mics, and they appear to be built very solidly.

Welcome! Post some good resolution pictures of the inside of the microphone.
Possibly in a new thread so as not to pollute this one.
Thank you, I will do that when I get home tonight.
Figure 8 is fully working though? On both sides? With the null in the middle?
i believe so, but I’ll double check because I did it 2 weeks ago when I received the capsules and have been busy with sound gigs ever since.
more than a few people have complained that the k47v is too dark at the lower end of its tolerance range. Honestly, I'm not a huge fan of bright k47s, but after I refined the k47f i feel sort of like there is too much overlap, so i think i am going to redesign the k47v to be more like a vintage k47 (up 2-3dB at 4k instead of 1.25-2dB as they are now) so that there isn't so much overlap. this is still comfortably less than the 5dB of most chinese k47s, but definitely brighter. in some of the units i do hear it. one of the downsides of switching manufacturers is that our new plates will be way more precise, so the capsules won't have a wide spread of tunings. i won't be able to pick bright capsules or dark capsules for people who prefer each like i could before. you get what you get, and i have to decide what people get now. sometimes having tighter manufacturing is not actually better... i might make the k47v bright and keep the m7 dark, even though they could just as easily be tuned the other way around, as that's more what people expect.

i'll start shipping k47s tomorrow. i had some peeves with the chinese k47 saddle so i designed a superior version and they're printing right now:
(Cue Raymond Scott's "Powerhouse.")
No but legitimately this is what it was like watching my machinist program the new CNC code for the plates. It's such a small shop and he has real adult jobs to do that aren't humor me, so he had no choice but to automate as much as possible. At this point almost the entire plate is constructed start to finish by CNC, even the center plastic tap insertion. It's like watching a Looney Tunes assembly line where everything is done by big white gloves on sticks
Hi @soliloqueen !
I have sometimes wondered if through the long, intense, challenging and demanding journey towards a K87 as close as possible to the historical original, among hundreds of prototypes, you made, intentionally or accidentally, a capsule let's call it 'K87flat' which mounted in a linear, flat circuit, without deemphasis and in a correct headbasket/body, etc., to reproduce the frequency response (perhaps the behavior in general) of a U87i microphone or U87ai correct.
Yes, 3U does something similar, maybe others too, but in my ears not faithful enough.
So, in short, my question would be: Will there be a capsule like the one described above? ' Arienne K87F '
Thank you!
