How to Build a Condenser Microphone

This is a build of a Neumann u87 Ai condenser microphone clone.
Here are some resources related to this build I've found in random order for now. I hope to update this to be more convenient as I get more perspective on building audio equipment:

I came to watch the process and loved it. Very well done. However, understanding your main concern was $$$ it is a little funny that you spent so much time and money on this! Could have grabbed a used WA-87 R2 for prob $450. No machine work, no hunting down parts, no wasted Behringer B-2, no wasted time! If you're doing it for the love of DIY I can absolutely see why you went down this road though. This was a really cool project!

Thanks gang! You're so right, it would've been cheaper. I was in college at the time (before leaving to focus on music) and they had a program where they would give you $300 to work on a project, so I spent like $250 out of pocket :)

Nice. It was great to see someone fabricate their own mic body. 👍

[@currentcontentco]

Thank you! It fucking sucked lol :)

[@lord_vesel]

the amazing work deserves some respect for sure

[@vocalvisionstudios]

Subscribe then bro 🙏🙏

[@currentcontentco]

Thank you! Means a lot gang!

[@badtweed2087]

Really good effort!

[@edelryjunior]

Really nice to see all the steps there. It also shows how much effort you put into it. Glad you mentioned all the help as well :)

[@mrrgstuff]

Good build, though a lot of effort. Thanks for the video 😀👍

Has anyone tried the Roswell k87 mics? They use the same capsule but they order the body from China and then assemble them in California.

Creamy mids, soft highs, super present lows that can easily get boomy/boxy. Its a great mic that beats out more expensive options, every artist I record seems to love it on guitar, sounds very realistic. It has a signature "wetness" compared to most mics. Where it's unlike a u87 is how loose the low-mids sound, doesn't have the signature tight low-mids of the real thing. For vocals, I have to battle the lows and wield off-axis placements, but the fight is well worth the color and the price point. Unbelievable voice over mic.

To much effort keep it up❤

[@currentcontentco]

Thank you!

How did manage to peak at over 500?? This project is about 250 tops

[@currentcontentco]

I love spending money

[@rickt1866]

wait so you were using the mic to make this video?

[@xdsnakeop405]

nice bro

[@CharlieMayMusic]

Would love to hear how it sounds! Great work putting it together

[@LeylaOnAir]

you hear it the whole video

[@lowlow22]

Thanks for this video bro ! I try to do the same 🙏🏽🔥

[@currentcontentco]

lmk how it goes!

[@kenzorwings]

I have the same type of microphone and I want to upgrade it :))

[@dotbot3827]

Freaking wicked build! I might be interested in the behringer's stock capsule. Any chance you'd be willing to send it over to aid a dude's 'scrap' project? Keep it up man 👍

[@irunthis91]

How long did it take to receive your PCBs?

[@drosselmeier]

Respect to DIY master 🙂

[@Thecando]

Great vid! So the whole set of components from the vintage mic store turned out bad? Was there a difference in components that were used? Also, what JFETs did you use in each build? That can be a big issue for some of this. Thanks!

[@currentcontentco]

I totally messed up the first PCB's. I forget which JFET's rn, if i have a chance I will check
