Shootout of Nos 6sn7 tubes
@shkong78 Have you contacted the ebay seller about the noise in your 1578s? One of mine has noise with no music playing, some crackling. I can hear it from my listening position about 9 1/2 feet away. It's not noticeable while listening to music unless there's a quiet section. I love the overall sound and tone of the 1578s but don't think I can live with the noise. I've switched the tubes from one channel to the other and the noise follows. I contacted them about it and they replied with a question, which I have answered. Waiting to see if they'll offer a replacement. |
@big_greg I do not hear noise from the tube bought from Ebay dealer after playing it for 20 hours. I recommend you to play it more and see what happens. Some people claimed to have had cured the problem with re soldering pins. They said most Russian tubes have problem with noise. https://www.head-fi.org/threads/the-reference-6sn7-thread.117677/page-120#post-15647922 But I am going to see what happens with more break in. I like Russian tubes with excellent bass and nice value but some of them may need re soldering. |
@big-greg After playing 20 more hours, if you keep hearing noise, you can contact dealer about it. Another choice is to do re soldering pins. Some people in Headfi is of the opinion that it is better to do re soldering on Russian tubes. I will also consider my options whether I will try to do re soldering myself or send my tubes to who can do better job than I. |
