Actual tube was tested on the State-of-the-Art AMPLITREX AT-1000 Electron Tube Test System CERTIFIED ULTRA-LOW-NOISE MUSEUM SPECIMENS TubeMuseum tested tubes takes the guesswork out of the process of selection delivering you the best Audio tubes that there possibly can be. Question: I see various colors for the RCA name on the base of the tubes…. some are white, orange, and yours appear to be red. They are all Black base from the 1950 and 1960’s. Are they all the same exact tube ( sound wise)?Answer: I wouldn’t know unless I listened to each individual pair. The way a tube tests is important and that they are matched in tube-gain or what is called Mu, and Plate Resistance or what is called RP Ohms, as well as DC Plate Current. So, unless you heard several vintages ALL with the SAME EXACT test results it wouldn’t be a fair comparison, now would it? RCA changed the lettering color from white to red usually from 1950’s to 1960’s. The orange is the red that has naturally faded. You can be assured of receiving the best tubes from The Tube Museum because we accurately test and report the true test results. Sound is subjective and everyone hears differently and has different gear, preamps, speakers, and where the speakers are placed in a room also play a major part in room-acoustics. Try putting a speaker in a corner and the bass will increase, if a speaker is by an open hallway or open door that will affect the sound of a room. Wire, the other tubes, your delivery-vehicle; DAC, CD, turntable, headphones, etc. all play a part in the way a tube sounds. Also, NOS tubes needs to burn-in for 40 to 60 hours before they wake up from their 1960’s deep-sleep to really shine.Terms of AuctionBID 1 FOR A PAIR!

PRINT WILL VARY from partial to almost none, as this is a multiple item listing Fender Twin Reverb: The circuit used is commonly known as the AB763 circuit. Fender Twin Reverb amplifiers use four output tubes, of the 6L6GC type. They use six preamp tubes, consisting of four 7025/12AX7A types and two 12AT7 types. The 12AX7A/7025 is a lower-noise version of the 12AX7. 12AX7A/7025 RECOMMENDED BY FENDER IN THEIR ORIGINAL TUBE COMPLEMENT RECOMMENDED IN: – Fender Princeton Reverb – Fender Super 6 Reverb – Fender Twin Reverb AB763 – VOX AC15 – Fender ’64 Vibroverb – SUPRO AMPS – Conrad Johnson MV60SE – MARSHALL – DR.Z AMPS Fender “Twin-Reverb” 6L6GC x 4, 12AT7, 12AX7 (or 7025/12AX7A), 7025, 12AT7, 7025, 7025 Fender recommended the “7025 = 12AX7A” version in their 12ax7 preamp tubes GREAT FOR MUSICAL INSTRUMENT AMPLIFIERS THAT COME WITH 12AX7 TUBES!

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
