Why some preamps does not play music? Cold?
I tried different NIB tubes, both Sylvania though, while it did changed tonally, the issue complained about remained. I will try some other brand. However, it is 6sn7GTB therefore not to much choice to play with, unless try not GTB but that, as i understand, not recommended. Theoretically, are tubes in power supply might cause that? Guys, thanks for your time and thoughts. |
georgelofi, I thought we are all in understanding that "NO PREAMP RECOMMENDATION" on this thread. Moreover, if you read my responses you will learn that I already have 5 preamps, all of them are active, SS and tubes, but only one of them(tube) causing the issue which I’m trying to resolve here. This thread is not about "the best preamp". Moreover, been 20 years in this hobby I tried for a zillion times "strait wire" source to amp, as it was suggested here by many for many times, to be the best way. Guess what, i can’t stay that sound for more then 5minutes, because that sound is total chaos and mass, "all over", unbalanced and causes fatigue (in my ears at least) in 3 minutes. Once again, here, I’m trying to get an answer whether i can illuminate very specific issue in my otherwise favorite preamp. Thank you again for understanding. |
However, it is 6sn7GTB therefore not to much choice to play with, unless try not GTB but that, as i understand, not recommendedThere are plenty of 6SN7 types out there, and in a preamp I would expect that a GT, GTA or GTB could be used. You might want to check with the manufacturer on that. The big difference with the suffixes is how much voltage the tube can handle. 6SN7s, FWIW, are an excellent tube (the only bad ones being the modern Russian types) and so I would not expect that tube to be the issue, unless its microphonic or something like that. |
