buzz

Hello out there in Marantz land! I have been working on this beast of a receiver and it has been going pretty well thus far. The original problem was the main filter caps, one deteriorated internally but luckily it didn't take anything out with it. I did my own version of the restuffing them...

Hoping to get some help from the tube experts here, let me preface this with I am very new to electrical engineering and DIY audio (as in built a bottlehead crack and that's about it) so apologies for likely some incorrect terminology use. I purchased a unique tube headphone amplifier off...

I have been experiencing a bad, loud, and variable noise in my electric guitar rig. Here is the details of the rig (I will include as many details as possible since ground loops are tricky): > Electric Guitar (active electric guitar with on-board buffer, 9V battery, and On-Board Effects Loop...

Hey, my name is Lucas, located in Edmonton, and picked up an old RCA Victor. When I brought it home and turned the knob to turn it on, after a few seconds, a loud buzz sound emerged. I also can not get the table to turn--though I may just not know how to work it. I saw some similar posts to...

Hi dear members I am chasing/hunting down a buzz in the speakers that seems to go down (still present) when touching the metal stem of the volume potentiometer. Connecting the metal casing of the potentiometer to ground does not seem to make any difference.

I'm never sure whether to post requests for repair insight in the solid-state forum or here in the DIY forum. Hope I chose wisely... I have the aforementioned amp, purchased new back in the 80s, and it has served me long, hard, and very well, six nights a week for several of those years...

Hi All, having a weird problem with a Nikko Alpha 450 power amp I'm working on. I've posted here before regarding this amp and the suggestions were invaluable. I've re-capped the power supply as 1 of the big filter caps had leaked and wasn't even making contact with the board. The amp sounds...

Hello All, I have a Nikko Alpha 450 power amp that buzzes until warmed up (10 min or so), after that its quiet and sounds great. It's not a crazy loud buzz but it's certainly enough to annoy. A little backstory, I have recently replaced 1 filter cap as it had leaked and wasn't even making...

My brother's old AV receiver sounded great ... but had a buzzing hum coming from the speakers which became noticeable at really low volumes. The buzz remained the same volume and pitch regardless of input, volume, input mode, etc. It was present via headphones as well...

I am new here, and not a techie. I have a buzz on one side of my 901's. Problem is I can't identify which of the 8 rear drivers it is. I have changed the surrounds some years ago. Buzz is at those typical low frequencies, and also when a singer hits that high C that always used to distort...

Hi everyone, I need help trying to eliminate a hum/buzz I have between my Thorens TD 160 turntable and a Denon PMA-700V amplifier. Sorry if there is any misspelling, I am not english native. I was having problems with the turntable because it was only playing one channel intermittently and I...

Hi all, I recently moved to a new apartment and have since been experiencing something odd/annoying. My stereo setup (Sony TA-555ES - Dual 505-2 - KEF Q350) has started producing frequent high pitched buzzes, and I have a strong suspicion this has something to do with teh electricity wiring in...

We have had a Panasonic SC-HT95 for quite a while as the heart of our home theater system, and we've been very pleased with it. But now it's got a sporadic problem that we'd like to track down and fix if we can. It will be powered up and operating normally, doing any one of its normal...

New to the Dynaco world. My new to me Mark IV amps have an identical buzz that is too loud to ignore. They were partially updated prior to my ownership and did not buzz at the sellers home. I do not know the make of the boards yet but they are currently running 1 Sylvania 6GH8A on each board...

I have been working on am akai 206c deck for a bit now and I got almost everything working, except for a buzzing sound when it's plugged in. When not plugged in it does buzz a bit but it's very faint and basically in audible at listening levels. However when I plug the power cable in there is a...

MaliD Hi, Maybe somebody will be willing to help me with this problem. My Marantz PM-551 right channel started to make some weird inconstant buzz that is present even without any music or sound played. When I connect just left channel output to a speaker it sounds perfect. Here you can hear it...

Hello everybody, I have completely restored a MARANTZ 3200/140 set. I was inspired by the restoration of Patfont's, by the way, a big thank you! My set works perfectly, a warm and detailed song as I like :) I just have a small problem, on the left track I have a slight buzz. It comes from the...

I've been using this integrated amp constantly for the past 8 years or so, and the other day out of the blue it started to emit a very loud and constant buzz. It deafens out anything else. I've isolated the amp, connected it with another speaker and confirmed it is the cause of the buzz. I...

Hello, First I want to thank you all for the valuable information that helped me get my 1120 restored. I did the tone board that included noisy transistors and the power supply board. This made a big difference because I was getting random pops that would turn on the protection circuit and turn...

I have an SL-1300 that I got off mercari. Generally working very well. RCA's and Ground look original possibly. I hooked up to Pre-amp and I am getting general buzz. Ground is just loose wires no fork with plastic, maybe fork was cut off. When I touch copper directly while on the ground on...

i have this late 60s rca victor(vjt34L) console that hums when i turn it on. the hum goes away immediately after i turn it off. im pretty sure its the capacitors. when looking through the back of the cabinet i see one on each large speaker and one big one on the main control area. i plan to...

Hi all, The Thorens enthusiasts here helped me diagnose earlier problems with my TD-165's speed clutch and platter adjustment. I thank the community for that. Am writing about a new issue that's arisen with my TT. I think I am the third owner of this table, which is largely stock, except for...

Hello, I recently acquired what I presume to be a Sylvania Record Player from the 1950s. It plays records excellent without problems, however.... it has this buzzing coming from the speakers that can't be ignored when on medium/high volumes. It only starts when the record turntable is engaged...

Looking for a patient teacher to walk me through using a 'scope to find an apparent oscillation in a Kenwood KR-5600. I'd love the help if anyone has the time to try! There is a sudden hum/buzz current draw at the full open position of the Treble control. I'm thinking it could be oscillation...

Hi, Just bought a nice DENON POA 1001 power Amp. I love this 22kg baby But it is buzzing. Here are the result of investigations : - The amplifier itself is buzzing, the sound in the speaker is good, there is no significant hum. - Buzzing is present with or without source/preamp, with or...
