| Audire Diffet 1 hum Jmho, it’s not DC offset on the AC mains. I agree it could be a ground loop hum. For a test disconnect all source equipment interconnects from the inputs of the preamp. If you have a sub also disconnect any interconnect/s from the preamp.Plug the ... | |
| Can I use just half the biwire? @ scott_w I also agree with lowrider57 Something no one has mentioned, will the un-terminated ends of the bi-wire cable work as an antenna and introduce RF back into the output of the amplifier? You might want to send a PM to almarg and ask for h... | |
| Any Audiophile Fuses UL approved? Technically the fuse does not have to be safety tested by UL. For electrical safety it should be tested by an NRTL recognized testing laboratory though. NRTL recognized testing laboratorieshttps://www.osha.gov/dts/otpca/nrtl/nrtllist.htmlhtt... | |
| Wattgate 381 outlet:any comments from the owners? overhang,JMHO, you would do a lot better buying a Porter Port and save yourself over a $100.00. http://www.porterhouseaudio.com/Porter-ports.htmNote: The Porter Port is a Hubbell IG 5362 (20) amp duplex receptacle. IG, (Isolate Ground), means the... | |
| Equipment break in question You need to feed a digital signal to the DAC and have cables connected to the analog output jacks connected to the amp. If an integrated amp is used set the source input to the CDT/DAC. The amp does not need to be turned on. (That is unless the am... | |

| How to identify tube amp Looks like a kit to me. Maybe a clone. Your Uncle may have assembled it himself. Did he have a background in electronics?Note the printed circuit board. That helps somewhat date the unit.Can’t see the back of the unit, no picture. Just a guess an ... | |

| DC Offset Blocker/Killer - where to buy in the USA cleeds1,989 posts02-08-2019 10:48am Simply plugging it in to see if it buzzes isn’t the equivalent of a proper bench test. Agree. The AC mains voltage might be 115Vac - 117Vac at the wall outlet at the dealer’s store. The OP’s mains voltage migh... | |
| DC Offset Blocker/Killer - where to buy in the USA @ stereo5 As I said in an earlier post tomiiv30 needs to hire a Power Quality testing company to check the quality of the power in his home. Some electrical contractors may have the needed test equipment to preform the test, but most don’t. For ma... | |

BS! atmasphere6,979 posts01-03-2019 1:06pmDC blocking circuits are expensive to do right, and are very rarely needed. That’s why they aren’t included in almost any linear power supply I know of. You... | |
| Network cabling for BlueSounds' Node 2i Network server sfar1,339 posts02-05-2019 9:04amAnd, RJ45 is the designation of the type of connector at the end of the cable, not of a kind of cable. That’s the connector you normally see as the termination of any category of Ethernet cable. Who said otherwise... | |
| Network cabling for BlueSounds' Node 2i Network server boogerhead ,As for the minimum it only has to be as much as the Fios Router is rated for and your internet provider internet speed. More than likely cat5e is plenty. For future you could also install a cat6 or cat6a cable. If you have never worked... | |
| Tube amp buzz (amp, not speakers) Descent sized toroidal power transformers are usually the ones that buzz, vibrate, from DC offset on the AC mains. As a rule EI transformers do not buzz, vibrate, because of DC on the mains.I think the power transformer in the OP’s amp is a bobbin... |
