Influence of the delay amplifiers for listening characteristics

[PMA]

Federmann, here is discrete preamp and uA741 at 475kHz for expected output 4Vp. Also, a phase plot of uA741 (it falls to -10 ° at 180kHz, not at 475kHz)

Phase plots are simulated for small signal in MC!

I'm not talking about topology, I'm not talking about frequency. I'm talking about the delay expressed in angular extent.

For all amplifiers will apply: delayed 10 °, it would Vdif = arcsinus 10°

You are wrong 10 ° for 741 when 17.457 kHz, not at 180kHz!


Think, I wish good night.

Le it be...his students say: He was teleported from another galaxy...but brain was lost on the way....

Once again, recall the beginning and involvement. Certainly your involved 741 same.

We are adults, not your students, so let your stupid examples for them....

[Federmann]

I'd like just an amplifier with overall feedback. Scheme and delays.

Thank you very much.

[Upupa Epops]

Do you have still real results, Federmann ? Or only your never ending simulations ? We are tired by waiting....

[Federmann]

I asked about concrete results, not speech and repetitive questions.

Thank you.

Maybe mods might like to move this thread to 'Everything Else', there is nothing about solid state here.
