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.
