| Measuring A Capacitor Well, I tried the suggestion clarified by Herman. Buzzing still present. Now, I am going to try shorting the interconnect, and see where that gets me... | |
| Measuring A Capacitor In order to be perfectly clear, I:Turn the stereo offPut the shorted IC in placeMake sure Phono is selected as the inputTurn the stereo back onTurn my house into a smoldering pile ashes (just kidding)Listen for the dreaded hum on the phono inputTh... | |
| Measuring A Capacitor The IC to every input didn't work, so now I'm on to shorting the ICs. We'll see... Do I need to turn anything off while I'm doing this? I'd hate to damage my Vandersteens while performing this. Also, I have a question. Someone thought a cap is goi... | |
| Measuring A Capacitor Can I just make shorting plugs with an RCA cable I don't mind sacrificing? | |
| Grounding A Preamp All the inputs except phono are dead quiet. I do know how to wield a soldering iron, so I guess I'll have to get out the Fluke meter, and tear apart the preamp... | |
| Grounding A Preamp I didn't check the interconnects for corrosion. I did change the ICs that go between the amp and the preamp. allow me to clarify one thing: when I touch the preamp, SOMETIMES the buzz goes away, but not always. I figured that if I stopped the prea... | |
| Grounding A Preamp The preamp also has a 2 pronged plug. The buzz is coming from the speakers, and is volume dependent. | |
| Grounding A Preamp The TT does have 2 prong plug. To check if the TT was the offender, I completely disconnected, ground wire and all. the buzz was still there. To this untrained ear, it sounds like a 60Hz buzz, like you'd get from a fluorescent light, or a wall-war... | |
| Grounding Hum Never mind what I said in the previous post. The buzz returned. After venting my frustration, I went to turn the volume up on the preamp, so I could the noise while I went around the house searching for the source. When I went back to the preamp, ... | |
| Grounding Hum I finally (3+ days) figured out. I pass along this update in the hopes that it helps someone else out. The source of the hum wasn't grounding at all. It was airborne RF given off by a Kodak camera dock in a distant room. All I can figure is that t... | |
| Grounding Hum It's Monster Cable interconnect cable, if that helps. Besides taking the cable apart, is there a way to tell if it's shielded? | |
| Grounding Hum I've tried every suggestion, but still no success. I've even tried "shielding" the preamp, the amp, and the TT with tinfoil. No luck. Any other suggestions? I'm scratching my head so much it may start to bleed. | |
| Grounding Hum The situation gets weirder, and weirder....As any good technician will do, I disconnected everything from preamp, still a buzz. I even unplugged the TT! After that resounding flop of an experiment, I swapped out the amp. Still a buzz. So I've elim... | |
| Grounding Hum Here's some additional information, which may help:If I flip the switch on my preamp (NAD1155) from MC to MM, the hum reduced, but doesn't go away. However, it seems that I, then, act as ground, because there is a more pronounced hum whenever I to... | |
| Grounding Hum I just tried the separate piece of wire trick. That didn't work. Now, I'll try moving the 'table and see what happens. |
