Up for sale is vintagemicrophonepcb U87i PCB & Components
And I'll throw in a working APP992 opamp
I had an issue when I built my U87i popping etc.
Thought it was the styroflex caps like my other had issue with
So I installed a couple mica caps in their place, all i had.
No fix, and just wanting to get this mic rolling I ordered a new pcb and components kit.
I re soldered the small pcb and still same issue.
Turns out I had the backplates wired to the wrong pad :-[
Anyways, all is there, the small board has most components, missing the 470pF caps
And pretty sure I got everything else for the main board except transformer
$60 shipped
