Big Boys. Bad and Big!

Sylvania 6sn7GT, 3-hole, bottom getter "bad boys" are a step up from the GTA chrome domes. I know people like to recommend Ken-rad dark glass but fail to mention non-microphonic ones are very hard to find. Early RCA 6sn7GT are quite nice too. Since Russia is in the news so much lately, how about the Melz 1578, black plates with round holes? Some say they are the best sounding 6sn7 ever made, certainly the best out of USSR. I like them. |
You have 3 posts and you’re digging up a years old thread, just to knock AudiogoN and show your ignorance? How many tubes have you personally auditioned against or compared to 1940’s metal based, NOS, Sylvania 6SN7Ws? Have you EVER SEEN a Sylvania 6SN7W, in person, let alone HEARD one, in a decent system? "Some say they are the best sounding 6sn7 ever made" ??? This is a highly subjective(look up the definition) hobby and, "SOME SAY" is a VERY ACCURATE statement! What’s, "ridiculous", is your inability to recognize and accept those two facts. In fact, "MOST SAY", would have been a more accurate statement, based on actual comparisons, like this: http://www.dehavillandhifi.com/6sn7_vt.htm ".....forums like this are just a sharing of ignorance.....", AND- you’re fitting right in, with the rest of your (possibly)deaf, (obviously)inexperienced, (painfully)whiny, nay-saying ilk. "HEARSAY"?? YES- Some of us actually can HEAR differences(in the things that we physically TRY) and SAY it! |
I say let's revive this thread; there are more people now than ever looking for the best sounding 6SN7 tube and now there are more choices than ever with so many Chinese companies now making tubes and tube amplifiers. Psvane, Shuguang, and Linlai are all Chinese companies making very good tubes. I'm using a Shuguang CV181-Z tube for my 6SN7 tube and a NOS RCA 5691 tube for my 6SL7 tube and they sound very good together, The Shuguang is softer and a little laid back while the RCA 5691 is warmer and more forward sounding so they complement each other nicely. The Shuguang is really a 6SN7 tube labeled as a CV181 tube and it draws the same heater current of 600ma as a 6SN7 tube and not the higher 950ma heater current that the old Mullard CV181. The RCA 5691 does have a heater current of 600ma which is higher than the 300ma of the 6SL7 tube so you need to make sure your transformer can handle the extra current. My Chinese made RFTLYS A5 tube amplifier has pretty beefy transformers and it doesn't seem to have any problem using the 5691 tubes in place of the 6SL7 tubes. The transformer is only getting slightly warmer than before; it is not hot you can leave your hand on it for as long as you want. For those of you that are into NOS tubes, I've discovered a treasure trove of information that is still available on line. All 20 issues of the Vacuum Tube Magazine are available on line in .pdf format and can be downloaded for free. http://www.enjoythemusic.com/diy/0414/vacuum_tube_valley.htm I found a listening test done on many 6SN7 tubes back in 1999 on page 9 of issue #11 which gave each tube a numerical score. The top six scoring tubes were: The Mullard CV181 (ST shaped 1952) score 97 Sylvania 6SN7W (metal base ring, top getter early 1940s) score 97 Raytheon 6SN7WGT (brown base 1950s) score 96 Sylvania VT-231 (bottom getter WWII era) score 95 Sylvania 6SN7GT (top getter, black base early tri-plate 1950s) score 95 GE 6SN7GTA (1953) score 94 https://web.archive.org/web/20131122141643/http://www.jumpjet.info/Pioneering-Wireless/eMagazines/VTV/VTV11.pdf |
