vu meter

So I recently got a one-previous-owner silver Mark III (with 2 meters and 4 knobs on the front) that cosmetically and audibly is pretty much as good as can be (all original), with the main issue that the meters seem to be completely dead (obviously any 50 year old piece of gear needs a recap /...

Hello AK. I recently bought my dream amp, a CA2000. Sadly one of the meters appears to be cooked. It's such -20db and doesn't move at all. I tried to loosen the screw a little and tap the needle to see it woukd move but it seems pretty well sad. Also, the screw seems way more brown (burned...

I've been tasked to diagnose a CA-800 amplifier for a family member, everything works totally fine, but the power meters spike to 5/5 and the VU stays at maximum. I have the whole thing apart currently, not seeing any burnt resistors in the path to the power meters (or anywhere else really). Any...

Hello, Hitachi HMA 7500/8500MKII power meters needed.

Hello, I recently restored a G22000 and absolutely blown away by the clarity of the audio. However, the VU meters won’t working. I did some digging and noticed a burned resistor on the power supply to the VU meter, I patched that and noticed that the VU meters would respond when the unit is...

Hi guys, I’m facing an issue with one of my 170DC vu meter. It moves, but in a sticky way, it’s slow to come down, doesn’t move freely in the beginning of the scale, …. I tried to unscrew a bit the little screw, heat it up with my iron … it corrects the problem with heat but as soon as it...

Hello! Picked up my first A-1200 and have few questions on functionality. Should the VU's be working when using a line input signal from my phone or is that far too little power to get them moving? When I first powered the unit up the VU's were pegged, even with no signal coming in, just...

I read in an audio magazine years ago that if you never put the VU meters needle's into the red, you'll never blow a set of speakers. I don't really do any recording lately, however; I've been thinking about adding external VU meters to my various systems as an indicator of how hard I am pushing...

I just bought a TEAC CX-211 at a local 2nd hand store for $20.00 and, luckily, it works awesome, but one of the VU meters works fine (right) and the other (left) moves very sluggishly. I plan of taking it to my tech tomorrow, thinking maybe it just has some dust in it or needs a drop of...

Hi all.. >>>>Hold on, sit tight, don't hold your breath.... This is gonna be a longggggggg read.>>>> Got my Second SONY in beginning of April 2021. Bought it for € 85,-- ex shipment (€30,--) from Germany to the Netherlands. Never heard it play... and I did not touch it.. It was from a Guy who I...

Have just noticed that the VU meters on my recently acquired Yamaha P2200 have begun to act strangely. They both lie dormant then but shoot across the display every six seconds! The movement is not related to the music playing while connected to source (a Chord Hugo DAC.) Switched off source...

I bought my spec-4 with a crack in both VU meter windows. Luckily, the VU meters themselves are actually encased in a clear (acrylic?) case and can use the spec-4 without the glass windows. I've removed the broken glass, but I'm having difficulty finding a source for glass this small (2" x 4" x...

Dear all, I need your advice as I found my Yamaha CA-810 integrated amp VU meter does not work properly on the left channel. - Left channel needle goes and stays at the max (furthest right) after the power on. - Back to the min (furthest left) after the power off. - Only happened to the left...

aka NEC AUA-8000E aka MCS3865. Found two similar treads: https://audiokarma.org/forums/index.php?threads/help-with-idle-current-adjustment.578811/ https://audiokarma.org/forums/index.php?threads/idle-current-question-nec-aua-8000e-amplifier.893200/ but with no solution, couple of guys tried...

Snagged a nice looking KA-5700 from a garage sale for $15. Took it home and found that it sounds great, all inputs work, and all switches/lights function. The only problem is that the left VU meter shows no readings at all. Sound comes through both channels and the balance knob works great...

To prevent overloading the MC225, I was wondering if anyone had recommendations of external VU meters of some sort or other power output monitor. Any help would be greatly appreciated!

This pet project is nearing completion. Okay the colour scheme looks familiar, does anyone like the look?

I want to use a EM83 as a VU meter on my next amp, an OTL headphone amp. Today I threw together a test, using this schematics I found somewhere: It kind of works, but the sensitivity is waaaay to low, so it only displays a small flickering when I play music to the inputs. Has anyone here...

I figured since the big beautiful blue VU meters are such an iconic part of the McIntosh esthetic, you fellow mac heads might find this interesting: https://hackaday.com/2018/08/09/the-vu-meter-and-how-it-got-that-way/

Hi, I have an APM-200 which do not do anything when plugged in, looks like the power transformer is dead. The transformer has a dual phase AC output but I am not sure about the voltage. I think, I have seen the lamps are 12v, so could it be a 12v-0-12v output. Also the power and watt switches...

Hi, my first post so please be patient with me. I have a Teac 4300SX which runs and record fine except : 1- In reverse mode as soon as I push reverse button the tape slips out off the guide. It plays fine in forward mode. 2-When I record a song I have to crank up the the input knob to have the...

So let me start out by saying that I am 19 and have very little experience with the intricacies of a nice HIFi system. With the help of my Dad and seeing what comes up on craigslsit and eBay I have a decent enough setup. Here is what I am running right now. -JVC KD-55 Cassette Deck (Not looking...

Hi guys, I wonder somebody could shed some light on the issues I've been having with my Ra- 414 integrated amp. First and foremost: the amp still plays well on all inputs, and both channels work fine. But: - The VU meters don't work while playing music, but they will jump to halfway the scale...
