Hi Steve, Just came across your site while searching for manufacturers of custom VU meters & least to say was blown out with your work on the audio meter, and would like to say, thank you very much for shareing it. It really goes beyond anything I've seen so far in term of features. Again, Thanx.

For the poster regarding the electrolytic caps (Name?): Actually, two back-to-back polarized caps are the same thing as a so-called nonpolar electrolytic cap, so the circuit is okay as it is. Thank you for your interest, though. --Steve

Electrolytic capacitors don't like to see reverse polarity (they tend to spill their guts rather dramatically). Therefore, C2 & C3 (on the input) should either be a single nonpolar unit or each capacitor should have a (fast) rectifier across it to ensure they don't see reversed polarity. Assuming your target is 50uF total, each capacitor can then be reduced to that value.

I still think this is a really cool DIY project. Has anyone else dipped a toe into this one?
