| Tube preamp noise I got NOS Sylvania GTB tubes and 1960's Russian tubes. They sound equally good, but got Russian tubes at the same price as Chinese ones, much cheaper than Sylvania tubes. Sounds notably better than the Chinese.For the microphonic noise, the Russia... | |

| Tube preamp noise I could not notice any microphonic problem with the new Chinese tubes. I have 10 used 6SN7 GT/GTA/GTB tubes form GE, Sylvania, and EH, and they all suffer microphonic rather severely. With a gentle touch on the amp case will generate an echo on th... | |
| Tube preamp noise "You might buy some new production 6SN7 tubes...like Shuguang...and install those. The new tubes should not be microphonic, especially if they are purchased from a dealer that screens for this problem."I got Shuguang 6SN7, and yes, I found they do... | |
| Rogue Magnum 99/ph vs PrimaLuna Pro3 vs AE PH-1? I tried those two preamps on McIntosh 275 (with Klipsch LaScalar and Velodyne subwoofer) and Linn AV5105 (with Tyler Taylo 7U).I felt Magnum 99 worked real nice with MC, both the CD and phono. The sound stage was wider, the base was deeper, and mo... | |
| Top resistors "Of the lot that I tried, I rank Russian 6N8S tops, followed closely by Raytheon GT, followed by EH. "Is it common consensus in audigon?I've read from some other forums that Russian made 6N8S tubes are not as good as US made 6SN7 family tubes.This... | |
| Tube preamp noise Socket replacement? It is an easy job?How often a socket can go bad? Is it a common problem for tube amp/preamp?Thanks much for your help. | |
| Leave solid state amps on? Or turn off everytime? Turning a ss power amp 24/7 may not affect the life of any electronic components? | |
| Used Tube Preamp Suggestions Audio Electronics ae-3 mkii tube preamp cary audio.Currently for sale in agon at $800.My tube friend suggested this preamp for me, but I went for something that has an onboard phono. I am not sure whether it was better to go for this and a separat... | |
| Tube preamp noise Thanks,I may contact VTS later. The preamp is 4~5 years old and uses 4 6SN7s. It came with 4 sets of 6SN7 GT, and 2 GTAs and 2 GTBs. All tubes generated microphone tapping sound on tapping with the eraser end of a pencil. Small bumping sound appea... | |
| Tube preamp noise Many thanks.I will try to find a bad tube. Well, one of my friends is a strong bias on tubes and almost forced me to buy a tube preamp when I was about to upgrade, but I am not new to tubes. I may be forever like that. ;-(Anyway, thanks for your h... | |
| Harsh on tubes? Many thanks.But I am confused:> the tubes are still subjected to deleterious thermal cycles if the preamp is not left on 24/7> you may face premature tube failure if you leave the unit powered up 24/7So, what would be a best practice to save... | |
| Albums you use to test your gears? "use your favorites"Yes, that is very true. Actually that is what I am doing. I have a decent amount of collections (500 CDs, 500 LPs). I just needed an additional help.It is both fun and pain on doing this.Fun part is if I recognize the sonic imp... | |

| OK to use unmatched or different brand tubes? They are used but tested as like new. So I would expect they are in good shape with their original condition, or close to be labeled as NOS. I spent more than a dime ($8 with shipping), so not a big deal. If they produce less quality sound than th... |
