Adding VU meters to DIY Amps

[LondonLad]

Hello,

How difficult would it be to add VU meters to a Purifi amp assembly I recently completed (https://www.audiosciencereview.com/forum/index.php?threads/diy-purifi-amp-builds.10478/)?

I don't know where to start and so I'd be quite grateful for any suggestions and/or directions.

Cheers.

Whatever you do, don't be tempted to slap an unbuffered moving coil meter across an audio path as this can cause significant distortion.

You would want something with a high impedance input that takes the audio signal and does whatever is necessary to drive the particular meter properly. Last time I checked there were different boards for this available from various sellers.

There are a bunch of blue backlit vu meters on ebay if you want to take that route. I searched "McIntosh vu."

I'm curious about adding a VU meter to an amp and I came across this:

TEK vomit backlight
https://www.audiophonics.fr/en/scre...db-with-calibration-module-115-mm-p-8342.html

The 'vomit backlight' is 'white' and it comes with a 'calibration module'
The impedance is 650 ohm +/- 10%

Thoughts?

Looks "built for purpose" to me.

It's illustrated as an add-on to a power amp.

Interesting comments in the reviews. Might need a mod to work well.

Odd choice for a name (at least in English)

Fred, hello and thank you! Looks simple enough to hook up, but please anyone chime in if I'm overlooking something in terms of my assessment of how "simple" that hook up actually is.
