Re: Super Low Distortion Ultra Pure Audio Oscillators Revisited

I decided to AC-couple the input to the instrumentation amp input. I stock 0.33µF polypropylene and tested them in this location. They didn't add any measureable distortion or change the signature in any way and are working at a very,very low level since they're after the notch. https://proaudiodes...

Re: The Corona Virus Hoax of 2020

I find it hard to believe that he would publicly suggest killing old people. Those ted talks must be pretty edgy. Ted Turner chiseled "The Good Club's" goals in stone at the Georgia Guidestones. How much more obvious do they have to be before you see this JR? They started with the aborted babies an...

Re: The Corona Virus Hoax of 2020

Gates makes similar comments at the Aspen Institute. https://www.youtube.com/watch?v=03MZG9vK0W8 In his world old people cost too much. "We" could be paying teachers... At TED and elsewhere Gates also talks about that "If we do a really good job at birth control and vaccination we can bring those nu...

Re: The Corona Virus Hoax of 2020

It does raise the question of why invest in trying to protect those with the least years remaining but this is a political decision not economic. Bill Gates summed it up in his Ted Talk. Old people cost too much to take care of. Soft-killing them with vaccine is low-cost and he can make money doing...

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

I was looking for the TL072H which they don't yet stock instead of the TL074H.
That explains why I didn't find any. :oops:

Also checked the TI store.
At the moment only the TL074H in SMT is available.

Re: Mid Side M-S Matrix Construction Information

Wow, the jigs and results are impressive.

What is the wrench in the top right-hand corner of the first frame?
I have one of those in the garage that was my Dad's.

I have a letter and number punch set similar to yours that I inherited from either my Dad or brother.

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

I checked and digikey has inventory on both H and non-H parts including TL07x from non-TI vendors.
Can you send me the link to the TI "H" parts?
I couldn't find them on Digi-Key either.

Re: Mid Side M-S Matrix Construction Information

Nice!

Did you CNC those dimples with one of your tools or did you have someone else do it?

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

Thanks for checking Digi-Key.
I had looked at Mouser and on TI's own product page and couldn't find them.

The one thing that didn't improve is the noise performance.
