U89 PCB Diagram 6 with Soliloqueen's K47 Capsule?

[TIDStudios]

So I just got my u89 PCB on (not gonna say from where so dont ask). I'm thinking about going k47 instead of k87. I want that to vintage sound however I'm wondering if that transformer will make it too dark. Any thoughts on this idea? Thanks

The transformer should not make it either dark or bright.
For the k47 capsule you need to disable the de-emphasis network

Only DC/DC converter is common with U89
Audio circuit is from U87ai.
C105 160pF styroflex should be removed

Thank you!OK so remove this and what else is needed to get the k47 to work with this cb?. And figured its was the u87ai PCB it's looked familiar

That's it.
But if you want more bass you can increase C104 (47nF) even up to 150nF.
IIRC @RuudNL increased it in his U87ai to 100nF
