Supratek Tubes and Tube Swappin' for Everybody


I will have a Supratek Chenin in my set up in a day or so. Since so many folks are rolling tubes around here I was hoping to garner a comprehensive list of everybodies favorite tube compliments. Be it NOS or NIB or WLATB (Whatever's layin around the basement)
Being that the "Deal of the Century" thread is a little more like a novel I figured this would be a good place to post questions and answers related to one subject of Supratek amps and pres.
On to the subject of me. I don't have immediate plans to swap tubes as I've figured that Mr. Maloney would supply us with something listenable for the break in period. But, since so many have reported such dramatic improvments I want to ask this question:
What is your favorite compliment for quietest gain and dynamics in the phono stage?
I will be using the Chenin exclusively for vinyl ( I don't have a CD player) and listen to loads of early rock and roll and Jazz bands, smaller jazz bands mostly, quartets and quintets. Some classical, the usual Beethoven and Mozart, but usually just a lot of loud garage rock.
Ok, now lets see what happens.

Thank for info, I have though that Marconi is Italian company and Osram German company ?
Is there a difference in sound between gray glass or clear glass GEC, Genalex ?
The Marconi companies were named after their famous founder, Guglielmo Marconi. He was an Italy, but he established and operated his company in England.

The grey glass version is usually regarded as tubier sounding: a bit sweeter, richer, and warmer. The KT66 did go through a few changes with it's oxide plate coating, which probably explains the differences in sound (likely has little or nothing to do with the graphic coating on the glass).
I have a Cabernet and am looking for suggestions for the PX4. I would like to replace the stock tube with some sort of NOS (or just old and good) tube. Which brands have people tried and liked?

Thanks
Hey Gang. There was a PX4 that was developed and manufactured by Genelex back in the 30's. It is extremely rare and very highly sought after in Europe and Japan. Like the original PX25, next to impossible to find. A pair would typically sell for more than your cabernet.
