| I’m getting a hum in my integrated tube amp and it’s bugging me alot OK, I finally have an update: the amp has visited the manufacturer (Roger of Roger’s High Fidelity). Roger said that my hum was due to 2 (of 4) bad KT150 tubes. He had no explanation for why my new matched set of KT88 tubes were producing hum (at ... | |
| I’m getting a hum in my integrated tube amp and it’s bugging me alot Again - sorry for the delayed reply, am currently traveling. I powered on the amp with just the speakers connected and the hum was still present. I will try to power on the amp with nothing connected; my best guess is that the hum will still be p... | |
| I’m getting a hum in my integrated tube amp and it’s bugging me alot Just spoke with Roger (of Roger's high fidelity). While he could not hear the hum in the new video that I sent, he did take my word for it and asked that I send the amp back to him for evaluation and repair. He asked that I wait until early Decemb... | |
| I’m getting a hum in my integrated tube amp and it’s bugging me alot Sorry for the delayed reply……I appreciate the responses. I have previously sent a video with sound to Rogers and he said he couldn’t hear it. He does stand behind his equipment, so I will give him another shot with a new video. I really like the ... | |
| Can my Roon Nucleus be used with a non-Roon-ready DAC? @brunomarcs - I use either an iPhone or iPad as Roon remotes. I occasionally use my iMac, but far less frequently. Very infrequently, I need to restart the Roon app, but basically, it’s been bomb proof. @big_greg - I brought my Nucleus over to my... | |
| Can my Roon Nucleus be used with a non-Roon-ready DAC? Thanks for the info everybody. I was actually able to get in touch with the DAC manufacturer, and he said that his DAC is Roon Ready. That said, I understand that as long as the DAC is new’ish, the Nucleus will be able to serve music to the DAC. I... | |
| Can my Roon Nucleus be used with a non-Roon-ready DAC? JJSS49…..helpful. “A DAC doesn’t need to be Roon ready.” I also realized that I made a mistake (newby, sorry). I forgot that the Nucleus would connect to a DAC via its USB output, rather than ethernet. So question #2 is moot. Seems like question ... | |
| I have a weird buzz issue; can you help me solve the problem? Yes, using single ended cables. No, did not try isolation transformer. It is clearly an amp issue which I will get fixed. | |
| I have a weird buzz issue; can you help me solve the problem? UPDATE: have spoken with CODA. They have heard of the buzz issue before (has something to do with the jumpers on the circuit boards). They said that pre-2015 units had about a 25% chance of buzz. The owner gave me instructions to bypass and test t... | |
| I have a weird buzz issue; can you help me solve the problem? So, here’s a weird one. The input shorting plugs arrived today, so I installed them (for the heck of it). Not only did it not impact the buzz at all, but.......it prevented the amp from generating any sound until I removed them all! Now I know for... | |
| I have a weird buzz issue; can you help me solve the problem? To oldhvymec: “You know what is strange, when you had a complete system swap a few years back it was even noiser. How does that play into it?”I suspect, but do not know for certain, that my previous house did have an AC noise issue. So that when I... | |
| I have a weird buzz issue; can you help me solve the problem? To imhififan: thanks for the explanation. I didn’t think this was an issue, but thought it worth asking the question. I was really surprised by how well the tube integrated drove my speakers......and it was almost a brand new unit with minimal bur... | |
| I have a weird buzz issue; can you help me solve the problem? UPDATE: I had the chance to borrow a new Prima Luna EL 300 integrated tube amp this morning. The amp was dead quiet! Clearly, I have a problem with my integrated amp. I will call CODA and inquire about repair. QUESTION: The Prima Luna had both 4 &... | |
| I have a weird buzz issue; can you help me solve the problem? To oldhvymec: my speakers only have one pair of binding posts, not two, thus I could not try your suggestion. I have multiple built in appliances in my house and thus could not unplug everything as you suggest. A previous suggestion was to turn of... | |
| I have a weird buzz issue; can you help me solve the problem? To cakyol: I tried your suggestion of plugging the amp and streamer directly into the wall (no power conditioner). It made no difference, the buzz was still there. I also tried just the amp alone into a regular outlet (no streamer); the buzz remai... |
