Will someone with an LM386 try this out for me?

[ExpAnonColin]

Will someone put this circuit on a breadboard?  I have misplaced all of my LM386's somehow...  First try testing the points labled +Vs/2, 0v, and -Vs/2 in reference to the circuit's ground, then try testing it using the LM386's output (pin 5) as a reference and let me know what you come up with.

Thanks a bunch.

my breadboard is full right now (with a 386 circuit, coincidentally), but if you send me your address i'll drop a 386 or 2 in the mail to you.

...when i get home, i'll do it...

what are pins 2 and 3 connected to...nothing ?
And what do you want tested, voltage...?

Yes, and yes.  Sorry if I didn't make that clear.  And if you could, try it with nothing in the pin 1-8 loop, too, because now looking back I think that that shouldn't make a difference.

claydavis-Thanks a ton, but I'm sure they're around somewheres... if not I'll just get some in my next sample order from National.

works, colin, and well at that...

I'm reading slightly less than +/- v/2, but i think thats normal.   I was reading about +/-2.3v, and thought that was bad, until i realized my 9v was reading only 5v  :x So I guess there has to be a slight voltage drop somewhere, but thats pretty good :-D

Instead of the pot, i used 2 430k resistors...But besides for that, i used all the same parts.

Little to no differance between with the stuff between pins 1-8 and without.

Still on the board if u need anything else...

Thanks a ton, Hal, glad my idea worked...  (Revises circuit, posts new thread)
