Tube Museum New York

..."Listening to these 1963 Cifte 6AU6 may be an unforgettable experience, just like a 1963 vintage Petrus. We have been fortunate to audition many different brands and vintages. That's why tube enthusiasts come to The Tube Museum New York for advice. First we advise you to choose wisely, and excellently. If you've heard a bad tube, which is probably why you are here in the first place - you're searching to find the BEST possible tube for your mic or tuner or preamp. A word of advice - purchase a NOS tube that is several decades old. Young Cifte's are impressive, it ages fantastically and requires more time to break-in than other tubes in it's culmination. Finally, we advise you to condition the tube with care, and give it time to develop in the mic or stereo gear or your precious tuner. Then you will have an opportunity to enjoy an unforgettable experience"... The Museum
