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)
