Great Sounding American workhorse tube, the 6U8-A reproduces sound with accurate tonality and one of the lowest-noise ECF82 variants . Superb affordable choice for hifi preamps and Guitar Amps. The 6U8"A" is a Low-Noise rated long-life tube made to last a lifetime.
Philips used color print and design for the special features as follows:
Green label: Originally Designed for computers, however, audiophiles have found this tube to be a suitable replacement for the 6U8. Designed for long heater hours, durability, high tolerance curve points, special cathode construction.
Nonetheless, all tube specifications change over time or don't change from the original factory testing, whether for Military, Industrial, or commercial, and they have to be re-tested now and today! That's why proper tube testing is necessary for any tube, regardless of what a color-code, or class of tube designates. Heater-to-Cathode leaks in a tube render it useless and too many of these undesirables are in circulation on the internet and sold by other sellers unbeknownst to them or perhaps they know and don't care. At the Tube Museum We care, Tube Museum tubes takes the guesswork out of the process of audio tube selection, providing the best possible audio tubes available.
