Hello, I found a simple VU meter using a 3915, but it only had one input. I found another with a more complicated power circuit that I don't want to use. I am wondering if I merge them as shown, if it will work. I am posting both circuits, with a merged photo also. Can I get some feedback please.
Wouldn't I need diodes on the inputs to keep them separated?
Thanks, adown
