Preamp Deal of the Century

Whoopadeedoo, in one of your prior posts I read about the Visseaux 6L6G or Mullard EL34 used as regulators. Now I´m using WE350B in my Cab. How you compare the 350B with any of those other tubes?.
My other tubes are Valvo GZ34 metal base, Sylvania 6SN7GT (1952) or Tung Sol 6SN7GT round plates and TJPx4/n or WE300B. Thanks

Jpms,
The Visseaux 6L6G (as with most 6L6 tubes in the regulator spot) are a lot more full and warm then the WE350B. The Visseaux 6L6GT (the straight bottle version) is not quite as warm as the 6L6G ST/coke bottle version. Having experiented more with the GT and G versions, I prefer the GT version because it sounds more controlled.

IMO, the 350B is an outstanding regulator for vocals. The mids and treble are on par or better then the other suitable 6L6-type tubes. The 350B has terrific spatial seperation and detail. However, I find it lacks full tonality. The bass is wonderfully tight but somewhat deficient in my system.

The Mullard EL37 is somewhere in between the 6L6 and 350B sound, and it is my preferred regulator tube at present time. It simply sounds the most balanced out of the group.

My head hurts...

Does anyone own any of Micks Amps? We all talk about how good the preamps are, but I would like to hear from some people that own a Supratek amp. What are your impressions? Is anyone out there interested in the new KT-88 based amp that Mick is working on? I own a Berning ZH-270 amp that I use with my Cortese, but owning a Supratek amp that would perfectly match my preamp in both looks and sonics sounds pretty cool.

Hi 65Mustang,The use of the 6F6gs as regulators may have never been known if it was not for Ecclectique bringing it to our attention here some time ago.I love them. When I first read about it I phoned Andy of Vintage Tube Services.I requested the best out of the bunch, he rounded some up and tested them and set aside acouple of nice pairs for me.Both Sylvanias,one pair 1930s N.O.S. matched to with in 2m.a. A secound pair from the 1940s ,carbinizied glass N.O.S.,matched with in 1 m.a.This is critical for the regulators to be matched to get the very best performance, be it these or any others you choose that will work in your Supra pre... Now here is an old radio /juke box tube that will have a major sonic impact on your pre,for very little money.I have seen the 6F6Gs and gts at a vintage radio show for 5 to 8 bucks each,all brands, some N.I.B.s.There are loads of them out there.Mustang,I know Im not telling you anything you dont know already,this may benifit someone else reading this.The power supply tube/s and the regulators have a major sonic impact on how your pre is going to perform...Just make damn sure the power supply tube test values check out.I have afew pair of rare and sought after 6SN7s .They all had their turns in my Chenin ,they were all good .I really had to listen carfully ,switching 6sN7s was nothing like the impact of changing the power supply tube and regulators,not even close.I ended up sitting back and enjoying what I was listening to.Even the new production E.H.6SN7s gold pins sound great,give them 50 plus hours burn in,another inexpensive tube.The phono section I have a pair of mirror matched R.C.A. 6c4s and a small fortune of ecc88/6922s ,Telefunken ,seimans and Philips Mini watt .cca,gold pins and S.Q.s ,only afew that are dead silent phono grade pairs.Buyers beware,looking for top N.O.S. phono grade? good luck.The Philips Miniwatt early 1960s gold pin S.Q.s are[out standing ]and a lot less money,very close in performance to the seimans and Telefunkens.I am very selective who I buy alot of tubes from,Andy of V.T.S. and a seller here on the Gon. from Holland. His user name is Dioto. Tom and Andy are with out dought straight shooters in this game,some of my very best 6922s came from Dioto.Anyway I hope this helps someone and good listening to all.
