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 Recommended for: McIntosh Tuners Microphones – Schoeps CM61 mic -Sony C37A and Altec 21 – C800G Sony mic – C37A Sony mic – McIntosh Model MR FM Tuners: MA 6 Multiplex adapter for MR66 x 1 tube MR 55 Tube.
