If the amp has a RCA line output, Via Tape Output if your amp has one of those or even using a Y splitter from the source so one signal from the splitter goes to the amps input and the other to the VU meter 3.5 mm jack input
Ground would be the shielding part of the input signal, ie the outer connection of the 3.5mm jack input or soldier a wire from the boards negative rail

I have been thinking of buying similar to these just for the look and fun
For a small outlay could well be just that
Hi Michael, great review of this interesting gadget..I'm quite tempted..
Just ordered one, for £19.81 inc postage. I will make a little wooden case for it, looks very responsive and good for the money.
How do I connect a vumeter to an amplifier?
