Help Needed for DIY Neumann U87 Clone Project

[NorbertJovial]

Hi everyone,

This is actually my first time posting on an online forum!

I’ve recently developed an interest in building my own studio gear, and I’d like to start with a condenser microphone—time to put my electronics classes to good use. My goal is to build a Neumann U87 clone, so I’ve been researching different options and sourcing parts online.

The PCBs from vintagemicrophonepcbkit.com look really promising, but I’m not sure if the website is still active. I sent them an email a few weeks ago but never received a response.
I also found a mic body kit on Studio939, but I have the same concern—no response to my email, so I don’t know if they’re still in business.

I’ve seen many websites selling K87 capsules, but I’m unsure which one to choose, and the same goes for the BV13 transformer.

So, I have a few questions:

• Does anyone know if vintagemicrophonepcbkit.com still sells PCBs?
• Where can I find a reliable mic body kit?
• What exactly are Styroflex capacitors, and can they be replaced with an equivalent component?

If there’s anything else I should know before starting this project, I’d really appreciate any advice!

Thanks in advance!

Salut NorbertJovial.
vintagemicrophonekits est bel et bien actif. Je viens de commander quelques pieces chez lui. Dany est un ami, je pourrais lui dire de t'écrire.
Ces kits sont supers. Pour ce qui est de Studio939, je pense qu'il a un probleme d'approvisionnement depuis quelques temps. Pour le boitier du 87, contacte Jenny de Ssyelectronics directement en chine. elle répond tres vite et ses prix sont bons. Je t'envoi son courriel en privé.
Tu peux remplacer les Styroflex par des ceramic MLCC, mais ca ne sera pas un clone du 87 qui lui utilise les Styros. Il faut faire attention quand tu soudes les styros, ils sont sensibles a la chaleur.
Capsule: Sans équivoque, celle de Arienne audio. La meilleure et la plus fidele repro de l'originale. https://store.arienneaudio.com/

While I'm sure the OP, as the rest of us, appreciate the friendly gesture, i believe the official language on this forum is still English...
