Title: What makes the LM358 in a Small Clone oscillate? *FIXED*
Post by: theundeadelvis on July 09, 2010, 07:53:26 pm

I've been working on an old Small Clone for weeks now. I've sorted through a number of problems, but the one thing I can't figure out is why I'm getting no oscillation from the LM358. The out put is almost completely clean, and I have no oscillation from pins 1,5, and 7 of LM358. The rest of the voltages look normal, and I can get some chorus if I touch my finger the 1150pF cap and D3 connection? Any advice? I also posted over at Aron's DIY Stompbox Forum, but my thread hasn't garnered much attention. Thanks!

Fixed - Turned out it had a bad LM358.
