Preamp Deal of the Century

Bob Malecki at Tubeseller.com is an excellent source of 6SN7's. He is not cheap by any standards, but honest. He specializes only in 6SN7's.

You can ask Bob to find a pair of NOS Tungsol Black Glass Round Pate 6SN7's and he will let you know as soon as he finds a good pair. He also tests all of his tubes prior to shipping and labels the test results on each tube.

Email him directly at tubeseller.com or go to his website www.tubeseller.com

The NOS Tungsols from Bob might cost in the $ 200.00 - 250.00 range (USD). The NOS Tungsols are quite expensive but well worth it. You also might find them cheaper, but I prefer knowing that I am getting from a trusted sourc\e and that they excellent tubes. Over time, the extra cost of NOS means little when you get great long lasting tubes.

I found that NOS tube take 2-300 hours to reach their potential. I noticed remarkable differences after 100 and 200 hours of use.

Good Luck and Enjoy the process

Well, I've got my 6F6G(st)s and I have Ken-rad and Tungsol 6SN7s. Now if Mick gets me my replacement umbilical I can give them a whirl in my Syrah. Note- I had to have one of the 6F6s replaced. Plugged it into a small Dared mono that I have to start burning it in, walked out of the room to let it warm up, and came back to a cherry-red tube, with smoke coming out of the base!! No flames, but they were imminent. Got it unplugged, cooled off, and fired up the mono w/another tube set. It worked fine, but I am quite glad it wasn't my Syrah that got lightly toasted. Lesson learned, never leave a new tube unattended when firing it up the first time. Any tube can be damaged in transit.

We will hit another milestone when we get to March 23rd, which will make it 2 years ago since you first started this great thread. Congrats & Thanks to you for getting this going and making us all aware of Supratek and Mick’s incredible pre-amps.

Hi again guys

Acording to the previous messages it seems that the 6F6G influences bass more than everything else. It gets deeper and stronger - correct? Well, I really do not need MORE bass. But TIGHTER bass would be much apreciated. Can you be a more specific on the bass improvement using 6F6G comparing to stock tubes and/or Tung-Sol 5881?

On 02-24-04 I asked this question and a couple more. I really need a word of advise here so I will ask again:

"For those who already tried the 6F6G I would like to know a bit more as for sound. How do they compare with (1) stock KT-66 and (2) Tung-Sol 5881 as for tight bass (less boomy)
sweet highs (less sibilant), emotional presentation (instead of clinical) and air"

Thank you very much.

Lisbon,

In my system I have found the Tung-sol 5881 to sound more on the warm side of bass. Good definition, but not the rock solid bass that you just feel in your gut. If I am using my Ken-rad's then I prefer the Tung-sol 5881's. I find the 6f6g's to be overkill with the Ken-rads, but with my Tung-sol round plates I love the 6f6g's! By the way, if you don't already have a copy or Brian Bromberg's CD "Wood", go out and get one. He plays a 300 year old upright bass that was made in Italy and with the 6f6g's the bass will rock your foundation. Man I love the hobby!
