For anyone who has a package stolen this should make you smile https://www.youtube.com/watch?v=xoxhDk-hwuo His other videos are good, esp the servo assist dartboard. I'm inspired by this video. If I sent a package from myself to myself and setup the Fedex driver for theft then I would have standing ...

... revealing test in an RIAA EQ'd chain. Exactly, I killed a lot of brain cells soaking RIAA stages in beer. Your comments WRT passive input pole servos has stuck with me. In the very brutal world of RAW playback the servo takes a high frequency beating. Once the servo op amp stops being an op ...

... quantify distortion of the DUT but now that you mention it it is a very revealing test in an RIAA EQ'd chain. Your comments WRT passive input pole servos has stuck with me.

... ; Output = -4.2 dBu J4-J7 linked; Output = +1.6 dBu J6 and J7 Open; Output = -10.6 dBu Frequency Response Measurement Frequency response with the servo switched on and off. With the servo off the preamp has response to DC. The green trace is limited by the response of the Focusrite 2i2. With the ...

... it cures it needs to keep being pushed down. https://proaudiodesignforum.com/images/jpg/ZTX851_MC_Preamp_Transistor_Therrmal_Hat.jpg This is the servo response ( at the servo output not the audio output) of one channel without the transistors glued in open air: https://proaudiodesignforum.com/images/jpg/ZTX851_MC_Preamp_Servo_Response_Without_Hat.jpg ...

I look at it this way: From a DC perspective if the output of the mic is a few hundred millivolts out of balance and the servo forces the resistance bridge back into sub-millivolt balance how is that any worse than it being in perfect balance to begin with? It can even be a good thing! ...

I would guess it would allow for large enough a correction, but it would need less attenuation at the output of the servo opamps, thus potentially adding more unwanted stuff to the signal. I intend to find out. I really like the ZTX851 MC front end and with mods I think it will ...

Olafmatt's servo that I used in the MC preamp works great at controlling the Vbe offset but I'm not sure it has enough range to also correct the larger offsets the mic presents. I would guess it would allow for large enough a correction, ...
