| Sharing ground wire between two dedicated circuits @emergingsoul You may find some of this information useful: Power Distribution and Grounding for Audio | |
| Hum on Tube Amp - Can't find source For those interested in monitoring their AC power quality, this is a cool little logger, which can also read some real-time values. Simple Logger® II Model L261 | |
| Hum on Tube Amp - Can't find source @ervikingo I'd love to look at the videos you posted, but I don't have Dropbox, and don't want to sign up for even a trial membership. Can you think of any other way to post them? After powering up the amps, how long before the hum appears? Do... | |
| Sharing ground wire between two dedicated circuits @emergingsoul If you’re going to spend this kind of money for two dedicated circuits, why not just spend a tiny bit more for the best? If they are truly dedicated circuits, with dedicated circuit breakers, their grounds should both never intercept... | |
| Hum on Tube Amp - Can't find source @larry5729 I read an article and they said tube amps hum. That would drive me nuts. Lucky you’ve never been there. The sound produced by tubes is many times euphoric, but that hum can drive some nuts (like me). IMO, sometimes there’s a trade-... | |
| Hum on Tube Amp - Can't find source @jaytor My amps have no audible hum with my ear up against the speakers. I’m glad to hear that. All tube amps don’t have hum problems, and all solid state amps are not hum free. I would agree with you. All of the tube amps I’ve ever owned... | |
| Hum on Tube Amp - Can't find source @ervikingo There’s been no mention yet of biasing. Have you checked it for all tubes? From the Manley Snapper manual, this is the rated Noise Floor spec: Typically 105µV = -77dBu A-WGT Typically 388µV = -66dBu unweighted. Depending upon how close ... | |
| Hum on Tube Amp - Can't find source I’ve had a number of tube amps over the years, both integrated and headphone. By design, they all produced some amount of hum. Even though I love the sound tubes produce (which in stereo mode, rarely ever 100% correctly sum to mono in headphones),... | |
| Phono stage hum at midpoint on volume control. @hiendmmoe -You list two different turntables in your components list. Which one is giving you the hum problem (or are both)? -Does the hum increase in volume as you increase the volume level? -I'm assuming you're not playing any vinyl when he... | |
| Only two tracks to test your system, forever! @prndlus Live FM radio broadcasts on WCRB of the Boston Symphony Orchestra. I have heard some of the broadcasts on their stream, and yes, they do sound absolutely amazing. My guess is the BSO employs someone to mix sound for them, and WCRB t... | |
| One dedicated circuit for each mono block? @immatthewj He did catch a furnace that failed the CO test, so I got that out of it. IMO, that right there paid for your home inspection. I was just wishing that the home inspector I hired would have pointed some things out for me. Someti... | |
| One dedicated circuit for each mono block? @jea48 by chance do you live in Chicago, IL or New York City, NY? I do not. I know why you’re asking 😊 - the WNEW-FM and WXRT call letters just happen to pop up in my system pictures. I’m a radio guy. At one time I was a big fan of both stati... | |
| One dedicated circuit for each mono block? @immatthewj I wonder what I paid the home inspector for 30 years ago. I don’t believe most home inspectors will make the seller upgrade outlets. They’ll now make them replace old fuse boxes, but typically the outlets can stay as they are. w... | |
| One dedicated circuit for each mono block? @immatthewj I think that I should pull some of those outlets off & see what I have got going on back there. . . . I would be very surprised if any of your 3-prong outlets have a 3rd wire ground connected to the outlet’s ground terminal (m... | |
| One dedicated circuit for each mono block? @immatthewj I am thinking I should pull one of those old outlets without the third wire and see what’s going on back there. It sounds like you’re referring to having an outlet with only two spade inlets (with no 3rd for ground). Yes, that was... |
