Re: New: A Direct-Coupled Input-Capacitorless Active Mic Preamp
Adding additional resistance to represent source impedance shifts both curves upward but large differences remain with typical 150Ω source impedances. Do those shifted differences track with this plot, or is the effect increased? This looks like 12dB difference at 50Hz, 6dB at 100Hz. In the zone wh...

Re: THAT4301 Analog Engine End of Life. THAT4305 adapter boards.
The attack release changes are interesting. Looks like changing the RMS cap, and trimming the input resistor are both necessary if substituting in an existing build.

Re: Analog "POTS" Phone Service - US Copper Shutdown Imminent
I don't know about ISDN, I would imagine they aren't taking orders. I haven't had a copper line in a dozen years or more.

Re: concept: saturator unit - transformer
As an owner of a zillion varieties of transformers, I find entropy has a way of destroying this concept - too many people with too many disparate aesthetic interpretations! To make something universal, you'd need to decide on a median level handling range, provide both attenuation and gain before an...
