Replaced capsule in 3 pattern mic but only figure 8 is working

[soliloqueen]

Ok, I’m happy and sad to report that the flat k47 in the other mic works correctly. I bet that the melted socket or some of the sloppy soldering is messing the 1st mic up. So, I’ll try wiring those pins to the circuit board directly and getting the socket out of there. I’m also going to check the joints on the extensions I soldered to the capsule wires on the first one, because I didn’t extend the wires on the second.

Worst case scenario is that I buy another mic and do it again. $70 for a learning experience isn’t so bad.

The reason I asked about whether the front diaphragm is at Ground in f8 is because it's also possible if you're supremely unlucky that the front wire was kinked against the lid in the box and during shipping exactly the right amount of internal strands could be severed leading to a front diaphragm that can be grounded but not polarized. You could also check the front lead wire for Sharp kinking damage at about the diameter of the capsule. My war against wire microphonics put me in a tough place. Neumann decided to use thick, mass and stiffness dampened wires. They can only make this decision because they make the entire microphone and thus have control over termination and can terminate the wire after a short distance in a way that doesn't really need flexibility. Since I don't have control over how the capsule is installed, I had to go with longer wires, which required different and more fragile insulation to keep microphonics down. It's one of the annoying things about selling retail and OEM capsules. I don't get to consider the system holistically.

Interesting, I will check that. I think I remember it being ok but I’ll check for sure. Given the fact that I didn’t accidentally melt any parts on mic #2, I’m going to guess that the experience of seeing how the mic was put together helped.

By the way, I had to use the stock post, and when trying to get the screw out from the original saddle, the difference in the stock screw and the screws that you supply is really evident. The stock screw head stripped right away on both mics and was very difficult to remove. That says something to me about your commitment to quality at every little spot in your capsule. Thank you for that.

Ooh, C15 got a bit melted:

Yeah, I have the steady hands of a sturgeon without a doubt.

It was the first thing noticed,
(sorry @157audio )
but it is not the cause of the incorrect operation in the present case.
Also, the microphone was built very badly by the manufacturer.
I think that we here in groupdiy really build at a professional level

Probably so. Maybe down the road I’ll look at building a different circuit for it from things that are around here. I figured out on the second mic how to get pieces out of the way of the iron in a better fashion.

Can't believe I missed that. The pictures are a bit disorienting haha

That's it! The sight gets worse, the hands start shaking, concentration weakens, we lose patience, health problems appear, but the important thing is to keep our enthusiasm and young spirit. Let's move forward!

I'm back and forth on it honestly. I do dig the high grade steel screws but they're also non-magnetic which is a bitch when you're trying to put them in the saddle. I'm thinking of reformulating them again. We're going to start making the capsule screws to order and I'm thinking about making the mounting screws to order too. It would be 10 times more expensive but 10 times more expensive than one cent is only 10 cents. But at the same time is that overkill? I feel like the day I start making the saddle mounting screws to order is the day I am officially insane.
