New u87 Body

[Khron]

Different cap values, different resistors value... What am I missing ? Is the ORS87 based on the U87i ?

And just how much difference (and in what direction) would you imagine the alternate values make?

While the idea is indeed based on the original U87 circuit, at least my version has a more... dare i call it, "sane" BOM (bill-of-materials). No point in needing 10-15 different component values, when five will do just as well (if not better).

Ok, thanks for clearing it up. I am not saying one is better than the other. But I would like to get closer to the original design here... and I already have almost all the parts, vintage NOS capacitors to play with, etc.

I am no microphone wizard like you and some guys around here, but I know what I like in the OG, and would like to give it a shot

Agggghhh! I feel like we’re so close to really accurate bodies, I wish these had working switches.

Maybe I’ll have to be the one to figure this out. I wonder if something could be 3d printed and use magnets to activate a reed switch…

Was wondering if you have figured out a way in the meantime?

Well, there is this U87 body kit now. I asked the seller if it includes switches, but I haven't heard back. It would be great if this was a viable option!

It looks like you have to add the magnets and the reed contacts yourself. Only the mechanical parts.

I think you’re right. I’m mostly interested to see if the switch actuators are included.

At some point a random guy offered this kit for around 300usd on the forum, and the post got deleted.
I think 211 usd is still a bit on the expensive side, and from what I see the PCB mounting is aimed at the AI version ?

Anyways, I have been working on a U87i PCB to fit the body discussed in the thread here, with the idea to make the gerbers available here for free, for the community and non profit use.

Stay tuned

IMHO the best part about that body is that one could interchange circuits and capsules.
