Circuit for analog VU meter

[G.L. Tirebiter]

I want to connect an analog VU meter to my gainclone. I've found some schematics for LED meters, but nothing for analog. Can someone point me to a schematic?

Thanks.

all you need is a ac meter. and alittle wiring

Uh, no.
A VU meter has a logarithmic scale, and a standard AC meter is linear. A linear meter is completely useless as a VU meter.

There's a circuit based on the ESP one (and a little better even 🙂 ) on my site: http://www.cheese83.freeserve.co.uk/amp/amp3/vu_meter.htm

That one got lost in a site redesign at some point, but there's a newer VU meter schematic here: https://mrevil.asvachin.eu/electronics/vu_meter/

is there a replacement for MC33172? can i use standard op amps like TL072?

 

[Mr Evil]

Any op-amp will do.
