mxl / schoeps circuit: how bad if I remove these two caps?

xeawr · Mar 2, 2020

Dear fellas!

Does anyone see any major problems in removing these two caps?

I understand they are there to stabilize the bipolar transistors, but the mic works ok with those removed, so my question: why bother?

These capacitors do little or nothing in the audible frequency range.

Probably just a high frequency roll off? Alright, I won't replace them for now...

... thanks so much for your contributions. This helps me so much in learning about electronics!!!

I don't think that's it. I'm pretty sure the Schoeps circuit doesn't usually have roll off which is why the Non-U87 circuit MXLs are so bright (same for the majority of the Studio Projects mics, and the Behringer ones too).

I suppose the main reason for these capacitors is to attenuate RF signals and to prevent detection in the PNP transistors.
