New here - need help for my planned u87 build

[arjun]

Hey y'all!
I'm basically new to the whole world of DIY microphones, and I'm just about to jump into my first build, however I do have questions. I want to build a U87 clone centered around the RK-87 capsule from microphone-parts, however, I haven't found a clear answer if the donor mic I want to get, the Behringer B-2 Pro, can fit the D-87L Large PCB from vintagemicrophonepcbkit. I do think the Behringer B-2 (non pro) was compatible, at least according to https://wiki.diyrecordingequipment.com/projects/vintage-u87-condenser-mic-pcb-set/. Does anyone know if this build is possible? Is there also something I should do differently? Please let me know, thank you!!

Hi @arjun
Welcome to GDIY!
There are two body versions of the Behringer B2-PRO, with different internal dimensions.
The older model has a removable head.
It appears that the older model
B2-PRO is mechanically similar to the B2.

Edit:
I recommend that you study the subject a little more before making a decision.
In the B2-PRO body I built u87 clones using the stock capsule, which is a very good 797.
In addition, there are already many useful parts, you only need a transformer with a 9.5:1 ratio and some easily accessible components.

Hello and thank you @micolas , I spent the last few days researching and have tweaked my plan.
I'm now looking at purchasing an unassembled Aurycle A460 (http://www.aurycle.com/aurycle-a460-large-diaphragm-fet-condenser-diy-microphone.html), ditching the B-2 pro for now. I still may also purchase the RK-87 to replace the capsule the kit comes with.
This however means that the final product won't have a polar pattern switch like the U87Ai and B-2 pro, and I'm a little unsure if am happy without it or not. I think It'd be something nice to have, but not completely necessary.
Please let me know what you think or if there are things I should do differently. Thanks again!!

This A460 Kit is too expensive and does not offer great quality.
It is identical to
T.Bone SC-450 which new, assembled, with accessories, with a 3-year warranty is cheaper:

You can find it second-hand for $40.
