Re: A Low Noise Balanced Input Moving Coil Preamp Using the ZTX851

I've updated this design with a new PC board. Hans Polak convinced me that I should use emitter servo injection to reduce ZTX851 matching requirements. In the process we discovered that huge improvements in IMD2 distortion could be realized by matching resistors and C4/C5. The 19/20 kHz 1:1 f2-f1 I...

Re: Flat Balanced Input Moving Coil Phono Preamp Construction Information

Updated January 25, 2021: A new PCB version, assembly instructions and Project Manager link are available. Improvements include a simpler servo, selected components to improve CCIF IMD2 distortion and an output pad for head amp applications.

Re: The TL071, TL072 and TL074 "H" Next Generation Enhanced Versions

The datasheet is confusing showing the same simplified diagram as the standard TL07x series but I doubt that's the case. With the OPA1612 (bipolar) and OPA1642 (FET) products they use a common emitter output stage (PNP on top) to get near rail-to-rail output. The output saturation numbers for the TL...
