Thank you for your response.
I had the 2011 datasheet. I now have the 2023 and see it. In some of the schematic examples the 10uF is shown as non-electrolytic. In the one for the AM receiver it is. Should that matter? That is, I do have two remaining 10uF electro caps. Can I use them or...
Klaus,
Thank you for your response. Indeed I was using an AC/DC adapter. (It was probably from an old mobile or small appliance.)
I knew it was an AC hum but I never expected it would completely overshadow the output.
Once I replaced the source with a 9V battery it worked great . . . for a...
I put together a circuit which is mainly the combination of two circuits I found on websites.
One is for inversion (inverting the left channel, combining it with the right and getting the result).
The other is a center channel.
The designs appeared in several places and seemed to be recognized...
