Hi I didnt want to jump into the U87 build thread with this.... Im gonna make a U87 type mic maybe from a kit or just by myself on a perfer board..... I only need cardiod really, I think I read somewhere there was a better way to wire the capsule if only cardiod is needed ..... Can anyone shed some light
I have been experimenting with a KM84/83 which seems very similar to 87.... Im trying to add the de emphasis section ( I think I know what Im doing ....) the circuit sounds great so far with a flat capsule no de emph good op level I have been reading kinda complaints about DIY U87 level being lower than modern mics ....Questions AMI T13 is 9.5:1 Cinemag 2840 is 10.5 1 fro U87 the KM84/83 call for 7:1 .....so why are they different wouldnt U87 be better off with 7:1....
Capsules..... before the U87 kits came along I was reading that the china K67 were good copies of neumann capsule but sounded bad because of flat amp circuits makes sense.....DIYers were using china K67s and were happy saying the the de emph circuit was making the chinas sound like neumann.....is tha the case would love to hear from anyone who can compare chinaK67 to the current crop of K67s & are the current crop made from scratch or modded or just sourced..... I did read the there are smaller 32mm versions too
So which is best haha silly question but here a little list would love to hear any thoughts on these capsules and more....As I say Im just need cardiod my my mic not sure if all these capsules will do all three polar patterns of the 87
Chnia free £000 with any shite mic haha

In my quick little bit of research I read some sellers offereing hybrids slightly different versions different sizes Advanced audio hav a less boosted high freq but I think I going to ignor those as circuit was optimsed for the original spec capsule.
