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 MuseumPRICE is for a MATCHED PAIR! FeedbackFromWhenA+++ Seller! The tubes are every bit as great as I have read about!

McIntosh MC7270 Power Amplifier LED Upgrade for Meter Bulbs

NOTE: You will receive the correct bulbs for your application, identical to OEM model, lumens, voltage, amperage, etc. There is no such thing as “universal” bulbs, beware of those who claim such nonsense. If you doubt my statement, ask McIntosh Labs directly, they are quite helpful. On more than one occasion I’ve had people asking about this. I am a McIntosh collector and currently own or have owned the majority of the models produced. Therefore I have actual real world application knowledge of these units and use these kits on my own units and not just copying other’s listings. This auction includes everything you need to update/upgrade your McIntosh MC7270 power amplifier meters, 8 LED bulbs for the meters. These LED bulbs generate almost no heat, are super long lasting, and are color matched to the original bulbs to give the OEM look./p> First picture shows a MC7270 after LED and Gel Filter upgrade. Amp is NOT included with this auction! “ALL MY PICTURES ARE OF ACTUAL ITEMS I PERFORMED SERVICE ON OR OWNED, AND NOT STOLEN FROM OTHER SELLERS OR WEBSITES, AND PICTURES ARE UNTOUCHED AND UNEDITED.” Free Shipping to the 48 continuous states.

Circuit designers are looking at Mu primarily, Rp next and we hardly care about Gm at all. Why then do most vendors measure Gm and Gm alone? Because most testers only measure Gm! No commercial tester ever measured Mu either (until the AMPLITREX AT1000 was introduced.) And even the Hickock, treasured for measuring Gm, doesn’t measure it meaningfully (due to current dependency), accurately (due to calibration difficulties) or consistently (due to internal circuit drift).'”… This tube is known for excellent performance, smooth highs, outstanding 3-D holographic soundstage, lots of open-air, inner detail, and overall perfect resolution and balanced sound.

Thanks! A: Fender specifies 7025 tubes in their later amps. I have seen tubes labeled both 12AX7A/7025 on the same tube. The 7025 and 12AX7A data sheets both say: …For high-fidelity audio-amplifier applications critical as to noise and hum… The 12AX7 data sheet simply says “For use in mobile communications equipment” the 7025 was a special 12AX7A for instrumentation, having low microphonics and noise characteristics. The 12AX7A was an ‘improved’ 12AX7. Although commonly known in Europe by its Mullard-Philips tube designation of ECC83, other European variations also existed including the low-noise versions 12AX7A, 12AD7, 6681, 7025, and 7729; European versions B339, B759, CV492, CV4004, CV8156, CV8222, ECC803, ECC803S, E2164, and M8137; and the lower-gain low-noise versions 5751 and 6851, intended for avionics equipment. 7025 / 12AX7A is $149.95 and out-of-stock at many internet tube sellers. Dear TubeMuseumUSA, just retubed my champ with tubes purchased from your store,fantastic,warmth,depth and harmonic complexity this amp did not have before(with 1975 production RCA’s),thanx for the quick/reasonable shipping to Canada,just added you to saved sellers list+entered 5 star feedback nice to find decent source those amazing N.O.S.tubes that my amp collection(and my ears) crave . – rickl642
