This is the small brother of a project i´m actually workin on.

If you see the wiring you won´t believe it works, but it does! And it sounds great 🙂

The schematics are straight forward with a TL074 for the inputs, a passive single pot panning circuit summing in an opa2134.

The LED meter is driven by two LM3914 display drivers at the end of the signal path.

I guess giving live time warranty to this would be fun 😀

Let´s treat it as an art project to create art …

THX to Markus who realized this none destroyable panel made of solid steel!
