<p>I designed this eurorack PCB which does that and a lot more, all
the way up to video frequencies if required. But it's eurorack so
+/-12V supply required.<br>

<p>In general your main concern with a wall wart is sorting out
negative supply rails. There are plenty of single supply op-amps
out there if you don't need negative voltages though. Or a switch
mode circuit to generate a negative supply rail from a positive
one...<br>

<div dir="auto">Hello, I've assembled a couple of video synths
that can be audio reactive but they need a bigger signal than
line level to work well. I want to build a 10x gain stage. Will
any op-amp work if I am using a wall wart that is dc? Any tips
would be helpful. TIA. JoeF.<br>
