I want to build this circuit to run some analogue VU meters:

VU And PPM Audio Metering

Problem is it needs +/-15V. Short of making my own PSU or trying to do some kind of DC-DC conversion, the only simple solution I can think of is to use +/-12V instead.

I think it should be fine. I will only be using line level inputs, so there should be plenty of headroom at +/-12V. Analogue electronics is not my strong point though so I wanted to ask some people who might actually know for sure

You should be more than fine with +/-12V, especially with line-level signals.

Thanks a lot, that's just the confirmation I needed. Will post pics when it's done
