I've got a D-87 (Dany Bouchard) that I've built into an Aurycle A460 mic body. I originally had it built using an Arienne Audio K87 capsule but I've since swapped it out for a JLI TSC-2 capsule (because I used the Arienne for my Fuchs U87a). With both cases I've been underwhelmed by the lack of sensitivity of the D-87 and would like to change it if possible so it's closer to what the Fuchs U87a would be (and my other condenser mics).
As is, the -10dB pad and low cut filter switches are functional.
I'm currently using a 33V Zener with a 47K at R17.
It's been suggested that the ORS87 would yield better sensitivity so I wouldn't have to turn up my preamp so high. I'm starting this thread so I don't pollute the D87 build thread anymore. Has anyone else done this conversion with satisfying results? As pointed out by @micolas I think it's just going to be a matter of tracing both circuits and removing what no longer belongs on my existing circuit board. Right?
