Re: Stereo VU meter kit BUILD THREAD

Perfect!

I put the 3k3 resistor in place of the 680 and it's working WAY better for me!

Thanks Joe!

Re: Stereo VU meter kit BUILD THREAD

Hi Mat yes they look fine. Any 2 clear white 5mm led around 1000mcd or more will work in there with the 680R. Each led has about 2.5 to 3.5v across it. So voltage at terminals will be 5v to 7v as the 2 are in series. They maybe brighter or duller so RLamp can be changed afterwards to make brighter ...

Re: Stereo VU meter kit BUILD THREAD

Yes. Very bright then turned/blew out.

I measured 12v at the led terminals. Is that acceptable?

Re: Stereo VU meter kit BUILD THREAD

Thanks Joe for replying! Yeah, no luck there with the new resistors and diode removal with the 4 jumpers. I tried a continuity tester with the LEDs and they appear to be blown. Would these be good replacements LEDs? https://www.amazon.com/Adafruit-Accessories-Super-Bright-White/dp/B00XW2MY84 All thi...

Re: Stereo VU meter kit BUILD THREAD

Update:

Looks like I miss this instruction.

The 2 x RLAMP resistors = 680R for new 5v LED Lamp meters and 8 x diodes are NOT fitted just 4 wire links as shown.

So I fixed that, but the voltage on the LEDs still clocks in at 11.57v.

Are my LEDs blown? Or just not getting the right voltage?

Re: Stereo VU meter kit BUILD THREAD

Hi all! The VU build was fun and relatively easy! I have not been able to get the LEDs to light up. There is voltage headed there which I am metering at 11.57v on each LED tap. Any idea why they are not lighting up? The VU meters themselves are working wonderfully, however. Thanks!! 63951564818__84C...
