Although they are not NOS tubes, I know ARC and Conrad Johnson keep supplies of tubes in stock that have to meet their stringent tests. The drawback is that they are least double the price that you would pay if you purchase from an independent tube seller. Of course, they are not going to be offering a line of tubes, but only the ones they use in their components. I think that most of the great tubemakers of the past are dead and with them part of the art of tubemaking died.
If you were a tube preamplifier manufacturer
We all know NOS tube prices are increasing and getting hard to be obtained day by day,there are several new production power tubes accepted fine performer such as Gold Lion Reissue KT88 and KT66,Shuguang KT88 SC, EH 6CA7,JJ KT77, etc.. among the audiophiles.
If you were a tube preamplifier manufacturer,which type and brand preamp tube you would choose from the new production tubes and why?,considering
its linearity,frequencies band from top to bottom, noise and microphonic clearness ,dynamic and rich midrange spectrum,etc.. ( I find some tubes are noisy or microphonic some has great top end but loose the bass region or just the opposite ...)
Is there any new production preamplifier tube being great performer like the new production power tubes mentioned above?
Thanks
