| Hum on Tube Amp - Can't find source @rhljazz Not treated. Thanks for the suggestion @papafrgog the closest access point is 20'away. I disconnected all wifi and low voltage and it didn't improve. Thanks! @redhouse6 I agree, I'll try on another location before buying something el... | |
| Hum on Tube Amp - Can't find source @atmasphere they are 20 years old. I just realized that the prior owner changed the input tubes to 12AX7 when the design calls for 12AT7. Thus higher gain (if my limited knowledge of tubes is correct) than what the spec for my particular version... | |
| Hum on Tube Amp - Can't find source Well, I can confirm it is not the alarm (which BTW I have reconnected!) @redhouse6 like a Triplite? I have a ZLC on order but it takes time to get it. | |
| Hum on Tube Amp - Can't find source @wsrrsw tried with Van Alstine Humdinger (for DC) but as described by FVA it only works to solve mechanical noise. I decided to try anyway. Also tried the iFi plug in things and even an old Tice thing (not the digital clock) waiting on a Ze... | |
| Hum on Tube Amp - Can't find source @dpop my house was built 5 years ago but the transformer has been there for years (i had the lot for 15 years before i built). Hopefully they’ll come check properly. The surge suppressor: https://www.grainger.com/product/19T314?gucid=N:N:PS:Paid:... | |
| Hum on Tube Amp - Can't find source @pinotnoir it is a dedicated line/breaker to the music room outlets. These feed the head units,4 monoblocks and a projector. Keep in mind, Everything but one tube amp is connected at a time as I try to find the problem. I originally had dimmers... | |
| Hum on Tube Amp - Can't find source @atmasphere Thanks for sharing your knowledge! I'll read more about it. I have asked the power company to come test their system. I hope they stick a tester to their lines before coming to see inside. I'm afraid they might take the easy way ou... | |
| Hum on Tube Amp - Can't find source @wsrrsw It ain't Hammer Time buddy! Noise is present even without interconnects | |
| Hum on Tube Amp - Can't find source @dpop thanks to you and all others staying engaged with my dilema. I’ve been at this for weeks. "After powering up the amps, how long before the hum appears? Does the hum then remain constant for the rest of the time after it first surfaces, or d... | |
| Hum on Tube Amp - Can't find source @wsrrsw typing from Phone is always a challenge, I appreciate your time! I did try a long extension cord to an outlet which is on a different panel (I have 6 panels at home plus the main panel at the interconnection with the utility). Problem w... | |
| Hum on Tube Amp - Can't find source Come to think of it, I always have my cell on me and my watch has bluetooth…? in addition to the alarm's cell. | |
| Hum on Tube Amp - Can't find source @dpop Once the noise starts you can't bias them as the voltage cycles. Having said that, they are right at 298-303 on all tubes (after many tries before the noise starts). @jerryg123 Thanks, I read the article and the discussion about it here... | |
| Hum on Tube Amp - Can't find source @blackbag20 who knows we already have “Our Lady of Blessed Acceleration”! | |
| Hum on Tube Amp - Can't find source @wsrrsw i haven’t yet but I’m about to. high end not “audiophile” outlets. Just tried again tripping every panel and breaker except for the amp’s outlets. Comcast line disconnected outside the home BEFORE the ground block (this nothing from ... | |
