Preamp Deal of the Century

Hello Lugnut,

Good to hear from you. Here is my favorite tube compliment in my Syrah.

Tung Sol 6sn7 Round Plates
Rogers 6f6g's or Genelex KT66's
Amperex 5842's
Mullard 6GK5's
Bendix Redbank 6106 or Tung Sol 5Y3's

The 6f6g's have a more dynamic sound, the KT66's have a more laid back sound with a fatter bass (good for the Jazz I like).

Hope this helps.

Lugnut - the preferred tube compliment will vary with your tastes. I don't recall ever noticing a recurring full tube compliment. There are definately some individual tube positions where some consensus has developed. Why don't you give us an idea what kind of sound you are looking for.

Try Hal-O tube dampers if you have issues with microphonic tubes.

Thanks Slowhand. That's exactly what I need. Jazzdude, I don't have issues with microphonics. What I notice is that very quiet 6SN7's are difficult to find. There is a background noise that is circuit noise. I'm guessing that since the tubes are so close to each other that they may be picking up noise from each other. I was wondering if anyone has placed a temporary grounded shield around each tube to lower the noise floor. No need for me to try this if others already have. Again, it's not that noisy and I'm not disappointed. Can't blame me for wanting it to be totally silent.

Hello Patrick,

Congrats on your Syrah! My recommendations for rectifiers and regulators are as follows:

Mullard Metal Base Gz34 - by far, the best in my set up. Followed closely by the regular black base variety. In my Chenin, the 6106 produces a "chugging" sound on the phono section, so I cannot use them. One good bargain is the Mullard "Dynaco" branded GZ34 you can find at Ebay often. Also, the IEC Brand but Holland made GZ34's are great.

The 6F6G's(I have Sylvania's) are good in mine as regulators. But I am currently using the Sovtek 6L6GC's that Mick recommends. Very cheap but very nice in my system. I bought it as a match pair (within 2%) for $50 plus shipping. I noticed a little "thinness" on the phono section with the 6F6G's but does not have it with the Sovtek. In my set up only of course.

As for the phono, your preamp and mine uses different type of tubes so I hope some Syrah owners can share their experiences with you. Oh, one more thing, I have the PSU and the Preamp on Audiopoints (the smaller version)and I really like the results. As if more clarity and definition (but does not upset the weight)had been added to the presentation. I think it has something to do with "channeling" the vibrations from tubes away from the platform. Maybe you will like it. Just aks Tom (TWL)about the points. He works for the manufacturer in which I am not affiliated to by any means.

Happy 4th!

Hello All, The tube line up in my Chenin is as follows.....Power supply, a superb [well burnt in] 1954 Bendix 6106. Regulators, A very early mirror matched pair of Sylvania 6F6Gs, clear glass ,old style round logo and etched base,very handsome looking .These are one of two pairs of 6F6gs I have.The Bendix and 6f6gs are [outstanding] inexpensive up grades in over all performance of the Chenin.6SN7s,A good pair of Tungsol black glass round plates.For me ,vocals have to sound right.With the Tungsols in place,Ella,Nat Cole,Sarah Vaughn ect.ect.are truly superb.One recent L.P. purchase,Joan Baez,Diamonds and Rust.The recording is one of the top best I have,the vocals captured on this L.P.are truly uncanny.I had a pair of Sylvania tall glass metal base in place afew months ago along with a used Dutch made bugal boy metal base GZ-34.Listening to Rock,Pink Floyd, Yes, The Who ect,I never heard them like this on a two channel system.It was a heavy experience.On Jazz and Folk,it was not as involving as my current choice of tubes .The phono stage,I use a mirror matched pair of 1949 R.C.A. black plate 6C4s and a pair of Philips Miniwatt S.Q. gold pins,the test values on these Miniwatts are outstanding.I did more switching of power supply tubes then any others in my Chenin.For me ,the Bendix is the one.One final note , my pre. is quiet as a church mouse...Love it.
