    akai aa-6200 receiver plug issue

    Dear colleagues, I want to know your opinion. Maybe you have an experience with this old amps/receivers. I have 2 prong unpolarized plug connection. I opened up and see the blue (hot I guess) and brown (neutral). The neutral is connected to chassis through 2.2Mohm. The chassis is the ground. I...

    Rega Brio buzz problem

    Hi folks. I bought myself a very reasonably priced 2nd hand Brio and I can see what the fuss is about. I love the sound of this thing. But......and I've seen a few reports of this, I am getting a slight buzz through the speakers and, more noticeably through headphones. Has anyone dealt with...

    Ground hum, Yamaha C4

    Have nearly tracked down the source of a constant loud hum. Think it’s the Phono MC input.. So, am wondering what should I especially check in the area of the Phono MC RCA inputs and pcb? Some background: Inserting a shorting plug into the MC Phono inputs has a modest effect on the volume...

    MA5100 grounding issues???

    I have an MA5100 that is very dear to me. 20 years ago I stumbled on a yard sale. They were using it to play music...... for the yard sale. I asked if they were selling it. They said yes. I asked how much. They said $15. And here we are. I adore it. After two recent back-to-back negative repair...

    Pioneer PL-50 Ground Issue

    I have a Pioneer PL-50 that may have a ground loop; it isn't a simple ground issue. The ground wire takes care of 80% of the normal ground noise, but at 50% volume (with no music) one can hear a lingering 60 cycle buzz and some hum when the TT motor is engaged. Frankly, this isn't objectionable...

    Pioneed PL-12D Humming/possible grounding issue

    Hi, I have an issue with my Pioneer PL-12D producing a pronounced hum. I have read threads on it, and people experiencing only one channel of hum and issues suggested to be the motor. However, with mine the hum seems to be both channels, it can go away when I fiddle with the ground wire such as...

    Technics F-G-Servo Player SL-23 Humming Issue

    Hello, I bought a Technics SL-23 turntable, and it played fine when the guy connected it at the store. I took it home and then found out that the needle was damaged, probably my fault, so I bought a new one and replaced the broken one. I have power speakers, which worked fine with my previous...

    AR-XA grounding problem?

    I restored (cosmetically, anyway) my old AR-XA from college. I relied on Vinyl Nirvana's DIY section for guidance, which was a great help. I decided not to attempt to rewire anything, at least this time around. I did replace the cartridge with a Shure m97x (I think that's the model). When I...

    Help with a buzzing Garrard GT-25P

    I keep getting a low pitched buzz in the right speaker, it is barely audible when idle but when I play a record it gets louder than the music and shows on the receiver's VU. At first I attacked this like a grounding issue or bad connection on R-, but now I'm out of ideas. I replaced the ground...
