This is a much improverd version of ECC88 made, with higher voltage capabilities, higher plate dissipagtion, and better in many many ways. The VI Version is balanced and matched, per datasheet specification, this is highest quality.
When you refer to finest datasheet details, they say they don’t need to know, they dataxheet already “30 years experience”. If you don’t know the answer May seem a silly advice, but it is a popular mistake.
Low noise version of 6N1P. Check also next item, below here. For a true happened story, read the world of NOS.
They test all at 15mA, with grid voltage variation of less than 0,2 Volt!! Here are the possible answers, only ONE answer is correct. Some tubes from equipment are sometimes actually never used. When it writes on there “ECC88, 1 ” as you see on the picture here this means this tube was made in Germany, indicated by the number “1”.
Also you should try the Svetlana types 6N1P. Factory does not excist any more: Set it on AC, and if nothing is read, set it on DC. To give you an idea, the size of a large bacteria is 5um.

This is a jewel. Leave it up to a technician otherwise. We have Money-back guarantee on those. Order nr for a matched and balanced pair: This may help you more than changing tubes.
So you take samples, you overload them for a ecc888 time, and when too many fail the whole lot is rejected. EHX new production under the microscope. The next three boxes are a short overview of the most important thing to check, in case of a problem.
Only do these measurements inside your amplifier, when you have experience with this. This is probably the best ECC88 ever made. JAN tested, for higher reliability. This tube excist as normal grid tube and as frame grid tube.
Is your ECC88 microphonic? The frame grid wire is so thin, when you open datashet a defective tube, you can not see it with the bare eye. Frame grid wires dataxheet be as thin as 10um, which is technologically speaking a masterpiece of fine mechanics.
They were supplied with first class tubes by the manufacturers, and the country of origin is always printed on the tubes. Click for high resolution picture here. This was told to me by a retired Telefunken Ulm Employee, so I think this is very reliable information.

All others are gone, gone, gone. Buy only from reliable sources! Sorry, only one tube left.
If you want a single you can only take the ones we have, we can not break up a pair for it. Anyway, not reading the datasheet may work with cec88 tubes, but not with all.

So if you order for instance tube 4 from this list, it is pre-matched with tube 8. These are no JJ Tubes. They are waiting for you there.
So all four systems of this pair are the same. This is not normal for E88CC, test values can vary widely, and you have to take them as is. Like this, and no other way!
