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

My latest observations revealed a very sharp rise in distortion at approximately a p/n junction from the rail. Indeed this sounds like something similar to what you describe. Also the negative rail does this at about 700 mV and the positive closer to 600 mV. They apparently have a different type of ...

Re: The Corona Virus Hoax of 2020 = 2021 "Vaccine" Shedding And Depopulation

When I was still living in Washington state in early 2020 I found this very document while searching through the many sketchy quasi laws they have on the books. Washington is quite beautiful and it was nice spending 15 years there, but I am finished with the west coast entirely for now and maybe for...

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

Digikey has/had them. These days you never for how long of course. The testing I have done so far looks noisy, but... the Ein for these measures in at exactly 18nV as do some of my very old TL072s, however... my latest TL072C DIPs measure in at 10nV! Under what circumstance the new ones would have t...

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

I am testing my first SOT-23-8 TL072H parts and it's "interesting". TI's data sheet(updated December 2021) that covers ALL of the TL072s is clear as mud in some areas. One being noise. Under the "H" version and "switching" it shows a whopping 37nV input noise density, however... they also list the "...

Re: The Corona Virus Hoax of 2020 = 2021 "Vaccine" Shedding And Depopulation

Keep up the good work Wayne. Making information like this public has never been so important. So many of the real "facts" and particularly real science get very little attention. The profound lack of real scientific evidence out there to prove the virus even exists is quite troubling to me. I do res...

Re: Super Low Distortion Ultra Pure Audio Oscillators Revisited

I am familar with dbu/dbm and dbv, but dbc? Is that a typo? This board assembled is very deja vu for me as it looks so 1990s industrial. I love that style of circuits. I have done some audio that way, however mine are mostly surface mount these days. Nice work Wayne. As precision oscillators go, at ...

Re: The Corona Virus Hoax of 2020

Published data has shown that there are several different factors that can contribute to the conversion of certain RNA binding proteins including TDP 43, FUS and related molecules to their pathologic states. These RNA binding proteins have many functions and are found in both the nucleus and the cy...

Re: Sound Semiconductor SSI Series SSM21XX Replacements

This is interesting to say the least! And I order from CE quite often. Thanks for the tip.
