EXTRA INFO:
LED PANEL (1st product shown) : YES...It is possible to snip off one of the power connectors and run the wires to the 5v in on the controller circuit board....but it's still rubbish....and yes I could have run a sweep tone into it to prove that it's faking the spectrum analyser and just flashing lights semi randomly....but that wouldn't really be adding anything, as it's obvious from just looking at it that the light patterns had little correlation to the music.

It seems to me like the first one has a threshold which triggers the particular frequency band to move, which then falls until it triggers again. It's not actually measuring the dB level in that frequency band.

I have an old Fidelity Playmaster tape machine from the 60's, which has the same vacuum tube level indicator, as you have here. It switches on when you set the machine to record mode and looks pretty cool. I must say - the even though the indicator valve is smaller in size on the tape machine, it definitely has a bigger 'dynamic range' - meaning thatwhen the signal is very quiet, the light columns are very short, almost not present. I found it very cool.

Been watching and enjoying your videos for a while. As someone who used to repair loads of old AV kit it brings back lots of memories. Saw a new tube base spectrum analyser using the magic eye tubes you have on the VU meter but using 6 of them instead of two. Chap called mr nixie makes them. A quick google for magilyzer brings them up. Certainly looks good.

there's an arduino library for driving the RGB Leds with extreme fidelity, and since arduinos can sample voltages, you could at least get 8 bits of resolution off each channel. I imagine if you used a set of bandpass filters in front of the arduino you could sample say, 4 pins per channel and get even more range (still each pin at 8 bits, but multiple pins per audio channel.) The LED Library is called FastLED, and can run hundreds (at least) of LEDs on a single pin. I've tested it with over 80 so far, and it can do it at 30-60FPS.

The AS30, commonly available as a kit, was also available on Amazon UK in pre-built form from a couple of sellers. I bought one in July (I knew I would mess up a kit) branded as DROK for only £35. It's essentially the same as the last device but vertical and more compact with USB power and a 3.5mm input both terminating in a USB mini-B plug. I've been very impressed with it, I use it on my PC for levelling the volume of applications.

I think that I will stick to my old tape deck/CD/mixing board/ receiver with a REAL VU meter setup. It may be 80's/90/s, but it actually works the way that it is supposed to. Plus, I can plug my guitar in, along with my headphones, and practice with only me hearing what I am playing. Plus, I can stop, reverse, and re-play anything that I want to. Thank you for reviewing these items. It just informs us that new items just don't work as well as they should, or are just pretty junk. The first one would be good around Christmas though! The red and green would be pretty with Christmas music! Great job, overall! KUDOS!

On the magic eye tube VU meters I uses a ground loop isolator because it was producing a whine, also a switchmode PSU makes noise which is picked up by the tubes circuits so I used a linear regulated supply to eliminate the interference.

The vacuum tube indicators should be bright enough to be visible in a normally lit room. They are very sensitive to undervoltage. They aren't very spectacular, but they work very well for their purpose - to actually indicate when you record too loud (with a transparant red marker in the middle), or for when you have tuned your radio correctly.
@johnr6168 5 жыл бұрын
Yes they were fine for domestic equipment. The dB numbers on mechanical meters don't mean much to most people anyway. The valve (vacuum tube) indicators were used in equipment which already used valves elsewhere so it made sense to use one more valve for the level meter.

I like the one that emulates the analog VU meter and the last one. Very good. The vacuum tube unit got my attention. My maternal grandmother, while devoutly reglious, was a bit of tech junkie back in the sixties when I was just old enough to be the same. She acquired a Phillips reel-to-reel tape recorder which she used to record church services and the like. It was a brute of a thing and weighed a ton. I remember having to carry that to the church for her on public transit. Anyway, it was only a mono unit of course and the record level indicator was in the stop button, which was larger than the others. It was one of these types of vacuum tubes. The plastic cover over the opening where it was housed, had a red bar in the centre, and if you went into that bar, the recording level was too high. It was all manual of course, no automatic level control. The tube in this machine was much more responsive than those in the video. It also indicated VU when playing back a recording. It was fun to see that they are still around in some form.
@VOmaker 6 жыл бұрын
I found a photo of a unit very similar to my grandmother's. I just remembered, looking at the photo, that the red bar wasn't painted on the plastic window, but on a sleeve that the tube slid into to mount it in the stop button. Unfortunately, there is no way to share the photo here. Or is there? www.vintage-radio.net/forum/attachment.php?attachmentid=94166&d=1402851825

Back in 1980-ish Aiwa made an add-on High Com II noise reduction box, the HR-50, for their micro hi-fi range. It wasn't very practical as a NR unit, because it had to be calibrated manually for each tape - but it had beautiful 3-colour LED VU meters which also worked in NR bypass mode. They crop up occasionally on eBay for about £90.

It sits horizontally in the chassis, and displays out the front in the tuning dial.

I recently made my first step into the hi-fi market, and away from cruddy all-in-one audio systems like the Crosley. I found a Realistic AM/FM Stereo receiver c. 1979-1983. It's got dual VU meters, as well as a needle that shows you how well you're tuned in when using the radio function. Eventually I also hope to purchase a good entry-level turntable and a cassette player/recorder, and I'll probably make a small stand to display the equipment on once my system is complete.

On the last one, I'm sure the LED bar graphs are peak reading. Most VU meters are not, unless they have special circuitry to make them peak reading. If they are standard VU meters, with standard VU ballistics, they would not show the peak clipping, where the LEDs will, so they are probably both correct, allowing for the differences. Nice video.

I bought a stereo LED VU meter off of a guy who puts kits together 3 years ago. It only cost $30 bucks at that time, but since I don't have a ton of cash, it did the job. It has 10 LEDs per channel (left, right) with 5 green, 3 yellow, and 2 red LEDs each. It also has a stereo potentiometer to adjust the meter level and a pair of RCA input jacks (left, right). All the components including the DC barrel jack for power are mounted on a clear, acrylic stand. It runs off 9-12vdc, and you supply the power supply. I just used a stereo splitter cable to connect my audio selector output to both the VU meter and amplifier. I didn't notice any change in sound quality by doing that. Although it is not to big and I don't have much room for anything bigger anyway, it gives me something to look at as well as provide me an accurate idea of how much power each channel is putting through the amplifier (without any numerical measurement). It also has an extremely fast refresh rate. This meter has also helped me identify various issues with my audio system down the road allowing me to fix them quickly. Although it is not big and super sophisticated, it does give me a VU meter like the one on a boom box we had back in the mid-'80s.
