Hello guys!
I started getting into building DIY and ventured into building a S-87 (condenser) from Microphone parts.
The microphone is getting good signal and all, but it's hissy! It's supposed to have a super low self-noise.
Interestingly, though, when I turn on the 48v on my preamp, during the first few seconds it's beautiful with no hiss at all and super clear but once the 48v seem to " hit" it gets pretty hissy 🙁.
Any advice? What components should I check out and see if they're properly working or properly soldered?
Thank you!
Hope to spend a lot of time here in the future 🙂

The lowest noise IC for microphone amplification is the Linear Technology LT1028 (although a bit pricey at ~$6 each!!).
Sorry to hear of your troubles.
Does the seller have any sort of support? Have you contacted them to see if they can help?
For anyone here to help, we need to see the schematic. Do you have one? I can't find anything useful on microphoneparts.com
