All tubes have Zero (0) Heater-to-Cathode Leaks!  Important!

- Heater-to-Cathode Leaks. Most tube testers don't show these leaks, and when even a small leak is present, it prevents the tube from reaching it's designed operating-point, rendering the tube useless in a short time, because it only grows with usage. We dispose of these defective tubes, others sell them to unaware buyers. 

- Microphonics. Most other sellers don't care, they sell noisy tubes. If you tap on them lightly in a circuit with pencil eraser they either thump trough the speakers or squeal. 


Only BUY THE BEST Tube Museum Tested Tubes ... 

Did you know that weak 6AN8A preamp tubes put an unnecessary strain and SHORTEN the LIFE of you other tubes in the circuit?

TubeMuseum tested tubes takes the guesswork out of the process of selection delivering you the best Audio tubes that there possibly can be.

TESTED AT REAL-WORLD POWER LEVELS 

ON AMPLITREX AT-1000

Tested on Amplitrex AT1000 Digital Tube Test System

..." * Rp or plate resistance is the second most important parameter as it directly affects the output impedance of the preamp. 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.
