A bit embarrassing but I assumed that all DC plugs was "tip positive". Now I know they're not. I switched polarity on the back of the DC connector and everything works fine now, including the opamp. Thanks for bearing with me! I gave it some legs to so it sits nicely just above my monitor controller. Happy with the product :D

Cool great to hear you got it all working :-)

Nice leaning it back behind the controller like that.

I've looked around and can't find much about this, but I need some info on the filtering with the new 5v LED meters. Does anyone have any good pictures of these parts in place (the 2 10R resistors and 2200uF cap) I want to make sure I'm placing them right.

Solder the 1000uF to 2200uF cap across the + - terminals on the VU2 standing straight up about 5 to 10mm off the pcb. Cut the 2 x 10R resistor down to have 5mm wire on one end and solder one to each of the DC connector terminals used. Then cut the other end of the 2 x 10R resistor ends down to 5mm and solder the red and black wire to them. Solder the red and black wire under the VU2 pcb to the + - terminals.

You only need to do this mode if the power supply being used is noisy and showing this noise on the VU meter.

I will try to remember to take a photo when one is next being built.

Thanks Joe!!

What you described is how I imagined it was supposed to go just wanted to verify.

And to clarify, would it hurt to just put these on from the beginning to avoid having to rewrite/solder?

Having the filter fitted there always means the power will be cleaner so fine to fit it permanently :-)

Hey joe, I got the VU2 all soldered up just have one last question.

After getting everything placed, I’m left with 2 100uf caps, 2 3k3 resistors, and 2 0R link resistors, just curious what these were for (I’m assuming old versions?)

The standard VU2 kit used has standard some extra parts not used in our stereo kit.
The 2 extra 100uF are for slowing down fast cheap meters to be more like VU meters - Not used in with in the stereo meter kit.
OR links for RLamp when running 12v lamps - Not used in with in the stereo meter kit.
3k3 for running leds in our 34mm VU meters - Not used in with in the stereo meter kit.

Joe :-)

Awesome thanks for the quick responses! Just finished everything up, this was a super fun build! Waiting on a power supply this weekend and I’ll have them up and running next week. Thanks again!!

Great to hear you liked building the kit :D 8)

Hi...those VU meters are pretty small. If you are after a nice RTR or tape deck VU meter style, you may want to invest in a VU buffer PCB or kit and get bigger VU meters. I have used JLM Audio VU buffer kit and it works great. More expensive though than the Ebay one you have linked to.
Realistic sold VU meters in an enclosure. You may be able to find them used.

Glad you like the VU Buffer kits. I am not sure which small meters and link you mean?
