interference

I have an old 1229 Dual that had a frayed 2 foot (original) RCA cable. I replaced it with a new medium-priced RCA cable which is 3 times the length of the old cable. (about 6 foot) so it can connect directly with my receiver without using extensions. Volume appears to be increased, and it does...

Hi all. I am looking for some advice. My neighbour has installed a radio tower the size of a 2 sorey house in their backyard (no planning permission but that’s a story for another day). With this amp, whenever I’m using the phono output, i can hear his broadcast which is conversation...

I have an SX-780 that plays fine... mostly. After around 20 minutes of use, the volume of the right channel will instantly increase (by a lot) with treble-y distortion... for ONE SECOND. Then, back to normal. 1. It has been serviced and had STK-0050s replaced last year. 2. It went back to the...

Hello! I'm not well-versed in audio matters regarding equipment, hence why I'm here. So heres the issue I've been having for months now: my left channel is making a weird noise, even if no audio is being played or if I set my volume to 0. Whether its my speaker or my open-back headphones, the...

Hi, I'm stumped and I really could use some advice on how to fix possible RF, EMF or grounding issues on the phono stage of my MA2275. It was just in the shop for 2 blown transistors controlling the bias of one of the KT88s. That issue was fixed, but as soon as I hooked it up, I noticed a...

I've been having this issue with my audio setup for a really long time and its time to finally fix it. When the line-out from my pc is plugged into the AUX on the back of my Pioneer SX-590 (3.5 to rca) there is a constant static sound in the background and also a bleeping sound every time half...

Hello wise sages of AK, I'm getting interference noise from my receiver, like a high-pitched screechy static noise in my right speaker. I know it's coming from the receiver because I hear the same noise when I plug in the headphones. So I was wondering would Ferrite beads work if I clamped them...

At first I only thought it was funny that when I hit the ON position of the light switch for my ceiling recessed LED spots (GU10 lamps) my tuners would instantly got full of interference... or noise... or static, you know what I am talking about. Everything ceases if I hit the switch to the OFF...

I have a Sansui 210 that I purchased to use at the office. There's a buzz in the headphone output when I plug it in at work, but not at home. I have an EE friend who likes to mess with stereos. He wasn't able to reproduce the buzz at his home, either. He opened it up and couldn't see...

Well I've been fighting with an issue with my computer to amp sound output. In a previous thread I started (link at the bottom, thanks @Oldsansui441 ) I indicated that there was a noise/humming in my Akai amp, discovering that it would sort of go away after pressing the bass knob. I did the...
