Any luck troubleshooting this? My only thought is to check all cables and connections and make sure the tubes are seated properly. Are you using an original Mani by any chance? IIRC those were known for picking up random FM transmissions.
No luck in isolating the source of the noise yet. It happens very random where some nights listening to music for 2 to 3 hours no noise at all. On other nights I can hear a mini wave of static interference that can last in between 10 to 20 seconds or so and then goes away.
I mostly lurk and rarely post but I’ve run into this situation with a few different amps. Many of my amplifiers, tubes or solid state have been antennas for Wi-Fi signals. If you have a strong mesh Wi-Fi system you may have to move the direction or location of the wireless router. I have a primaluna amp that would randomly have static noise coming out of the speakers, similar to what you described. I went nuts cleaning contacts, swapping tubes and cables. All it took to fix it was turning the wireless router (which was 10 feet away) about 45 degrees. Might be a long shot but I hope that helps.
Thanks for the advice. Will have to check that out.
I did not know that that phenomenon was possible! Something like that does make sense with Smootstereo's description of his issue. Would love to see if addressing the wireless router has impact here.
OK…my resistors are also soldered in now…I had an issue or two caused by lack of circuit board soldering experience…
I will be interested on what you think about the resistor upgrade.
Make sure you are familiar with the post cap mod sound before you do it.
…but I sorted that out and my unit is up and running perfectly and burned-in about 100 hours.
That’s great to hear. I’ve gained so much knowledge from reading these forums over the years, I’m glad I could give back. Tubes are wonderful for music but can be finicky. After reading this thread, I purchased one of the last closeout Freya Ns. While it sounded utterly amazing with my Aegir amp, it had a loud popping in the tube mode when moving the volume back and forth past the 12 o’ clock position. Schiit customer service has been nothing less than stellar as usual and instantly shipped me a new one. It’s supposed to be delivered tomorrow, so I’ll report back.
I hope the new one works out. I had the same issue with my Freya N. Two different units. I eventually gave up and got the Freya S, which sounds fantastic with the Aegir. Maybe one day I'll get a Freya + and jump back into tubes.
Sorry to hear about your experience, hopefully I’ll get lucky. I’m glad to hear you Freya S has good synergy with the aegir. I’ll definitely keep that in mind as an option.
pops are on the amp. My Freya S popped like crazy with my 90's mono blocks. When I hooked up a Vidar amp, pops were gone. Must be some sort of filtering on the Vidar that my old mono blocks don't have. Long story short, the Vidar sounded like Ass compared to the 30 year old mono blocks, so I just deal with the pops.
Just to jump on this and thank everyone for the advice in this thread-I was having a similar issue with trying to eliminate some weird noise/interference that was cropping up in my Freya N and Mjolnir 2 chain. So far the router does not seem to be at fault but after examining all of the weird things you would never expect I found the culprit (well the current one anyway). I found that one of the mice in my office, which happens to stay on as long as it is plugged into the USB hub (even if the laptop attached to the hub is off), was omitting a weird, almost inaudible squeal. It is a lightweight design with gaps in the structure that I guess were allowing the squeal to get out too easily. Anyway that mouse has been replaced with a different one and the issue has been resolved (for now).
Everything is better with the Nexus, but it's also a touch more lively. For my Tekton Pendragons, it's a bit too much for me. Now I run the N with 6n6p/6n23p tubes, and it's much better.
