Weird. With forum_default number of posts/page this thread has 311 pages now
I then cannot proceed to page 311, instead 310 is built twice. 😕
Setting posts/page to 30 heals that.
yeah I have had on some long threads. I run 50 posts per page as easier to sort signal from noise that way but blowtorch thread stuck around 60k posts and needed a change to read the next page. It's a bug, but one with a work around 🙂
These problems occur regularly for members. Solution is always the same, just run a full browser and disk clean on your PC to delete ALL temp files.
Setting your browser to delete temp files automatically (but still retaining log in details) each time it is closed stops these issues ever beginning.

LM334 works well. Also read this https://tangentsoft.net/audio/opamp-bias.htmlLooking at the diagram it is starting to make sense, thanks I got it now.
One more question, I am guessing you can get better performance using a current source to -Vee instead of a resistor?

Edit: I meant +Vcc

Thank you for the reference!

Theoretically? May be. Practically? I see no point.
So these 8 legged creatures work better when circumventing the functionality of some of their internals? I wonder how they design them....

Your choice: either save an electricity, or a sound quality....
So Bear I'm all ears, what did you mean by this comment? If I took it wrongly just correct me, no problem at all and we can move forward.
To try to attain clarity, I don't know anyone personally, who thinks that there are zero sonic differences between their master tape(s) and subsequent dubs, digital or not, we're talking directly recorded for maximum fidelity, minimalist mic'ing of the highest quality that they can manage.
They may or may not be delusional, etc...
...they may be splitting hairs...
It's mostly along the lines of an Indy driver complaining about his car not handling right in the turns, but he's comparing to another car that is doing a lap in a fraction of a second faster...
...but I rather doubt this has anything to do with opamps, if we're talking digital.

c'mon, why?
you surely know that pulling the outputs up to class A has some benefits in some situations.
_-_-
But that's obvious, it's the 1dB overshoot at 1.1GHz.
Yeah, right, of course...
... but a serious response would be more instructive.
since you are in possession of greater insights and understandings than myself, I'd like to know - since you did make the statement about "sibilence" with this device. Or was that a joke?

No, really, I mean it, and I trust my ears. Prove me wrong.

Because I found it funny when formulated that way.
Seriously speaking, the purpose of (A)B class is generally "moar power", but seeing how those 8 legged critters can't drive much, one may ask himself why they're done *only* that way.
Of course when I turned it on it oscillated, but I knew what to do. There have been more than one audiophile amp that oscillates on peaks into a difficult cable/speaker combination.
Scott, make one that oscillates at really high frequency and correct it with a stub instead of inductor.
Then when the box falls in the hands of a modder and he prunes the "stupid dangling wire" in order to reduce "noise pickup".....

Strange.
You want me to prove that you do not trust your ears??
By what magical means do you propose that I or anyone else go about formulating such a "proof"?
I take this as a fully sarcastic response on your part Waly.
Comments along these lines, by anyone, especially when they appear in multiple posts are not constructive, and so reduce the benefit and value of the forum. Dropping down the dialog to something that I would prefer to not describe.

Perhaps if your focus is so strongly on humor and being "funny" you might restrict your posts to the "Lounge" or perhaps another forum that is focused primarily on humor and being "funny"?

Humor or not, it's still a valid question regarding op-amp design.
the stub comment is?
you should know the reason for the power limitations in the DIP 8 package, I would think...

Tell me more on those power limitations, and how you need class AB to drive the next stage, especially when it has FET inputs.....
Waly, are you going over to the dark side?? 😉
I'm already there.

You moderator now? Did SY pass the torch? Or it just felt from an UFO?
