Also read here Uh-k. Frame grid wires can be as thin as 10um, which is technologically speaking a masterpiece of fine mechanics. These are no JJ Tubes. The next datennlatt boxes are a short overview of the most important thing to check, in case of a problem. For a true happened story, read the world of NOS. Large dimension ECC88, with higher dissipation.
Buy only from reliable sources!
Used tubes of this type generally have more hum and noise. For a pair, order two pieces, they are automatically packed as matched pairs if you do so. What is best, we had a small lot, and we have been able to select them all in perfectly balanced and matched pairs.
JAN tested, for higher reliability. Can’t find it here?
Assessment of The Microwave Tube Industryan inside look at what high-tech tubes are used for, why they’re used instead of transistors, what’s in them lots of beryllium!
So if you order for instance tube 4 from this list, it is pre-matched with tube 8. This is not normal for E88CC, test values can vary widely, and you have to take them as is. HQ tubes made for the Czech post, from the Rosnov factory Code Very good selected, and this batch has very high test values.
We have Money-back guarantee on those. Don’t try to be Mr. This is a jewel. Elektronska Industri, former Yugislavia.
All others are gone, gone, gone. Well, I think experience and detailed product knowledge is the same! Here is a Link to all daatenblatt reports. TESLA is even a frame grid tube! The negative result is, end users have to swap tubes all of the time, and desparately try to draw conclusions from this.
TDSL Tube data [ECC88]
Called Uf Test with Voltmeter between Pin 4 and 5. So with them, what you pay is what you get. Lucky on internet auction sites. The ones we sell, are “EB”, also when not dcc88 like this, it’s what they are. This was told to me by a retired Telefunken Ulm Employee, so I think this is very reliable information.
Like this, and no other way! Now that EI is closed sincecatenblatt of EI tubes are expected to soar. Read below, how to connect the voltmeter.
This is not possible for the most wanted part numebrs. In many problem cases, the ECC88 is not used correct.
So all four systems of this pair are the same. Even with top-name amplifier manufacturers we see the same old errors, resulting from arrogancy, like not reading a datasheet. Some more useful info: Click Here for sheeton Sovtek 6B4-G. The “Help,My Amp has ‘s! Sorry, only one tube left. You can order any pair you like, as long as we have it available. Original old blue boxes.
The frame grids have generally better parameter stability, lower noise and lower hum. Note that the newElectro-Harmonix A is now available,and it does not requireany rewiring to use. The frame grid wire is so thin, when you open up a defective tube, you can not see it with the bare eye. These tubes are boxed and branded “National” USA. So you can see it yourself. Perfect quality, good boxes.
