| 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... | |
| DC Offset Blocker/Killer - where to buy in the USA DC blockers are colored and roll off the highs. 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... | |
| Silly question about a KSA 250-Fuse @ duran Is this a picture of the back of the amp? https://www.ebay.com/itm/192768389378If so that is not a fuse holder. It is a 20 amp circuit breaker. If it trips you push in on it to reset it.. | |
| Tube amp buzz (amp, not speakers) Tube amp buzz (amp, not speakers)Hello - Almarro a318b makes buzzing sound at random: sometimes it does, sometimes it doesn’t, completely unpredictable. The buzz comes out of the amp itself, like a transformer buzz; the sound out of speakers is c... | |
| Life of KT150 tubes on ARC Amps veerapaneni OP107 posts01-30-2019 7:32pmI read they are good for 3000 Hours but at 2400 hours they are not sounding that great and always played at very low volumes. I am doubting the 3000 hours number now and that’s why i posted this topic orig... | |
| Life of KT150 tubes on ARC Amps fsonicsmith322 posts02-01-2019 9:44am It is no secret that ARC feels that fuses and other methods of circuit protection degrade the sound and also no secret that ARC’s practice of having a single resistor act as circuit protection for tube failur... | |
| Life of KT150 tubes on ARC Amps @ veerapaneni One thing you might want to check is the AC mains voltage at the outlet/s the amps are plugged into. The mains voltage can affect power tube life. Power tubes will last longer if the mains voltage is, say, 117Vac than if it is 123Vac... | |

| Life of KT150 tubes on ARC Amps jetter882 posts01-30-2019 7:11pm But somehow retube costs of ARC amps is a familiar topic here. Well thanks to gpgr4blu post, the KT150 tubes in the OP’s amps are good for up to 3000 hrs. | |
| Life of KT150 tubes on ARC Amps @ stereo5 Take at look at the OP’s 2ch system. I see $150K easy. Maybe not rich, but LOL, he sure ain’t poor. Jim |
