Printing is fainted, but unburned, very white still. You can order any pair you like, as long as we have it available. Page1Page2Page3Page4. Also you should try the Svetlana types 6N1P.
Leave it up to a technician otherwise. Done so in when these were made, but JAN testing is still used for semiconductors as well. This is not possible for the most wanted part numebrs.
Used tubes of this type generally have more hum and noise. Made on Philips machines. This is a very hard way of testing, since “good” tubes must still be rejected when they come from a production series where too many have failed the JAN tests.
Datenbpatt directly compatible to ECC88, so a secret tip if you can design your won circuits. JAN was the first choice, the rest got sold commerically. When you refer to finest datasheet details, they say they don’t need to know, they have already “30 years experience”. Don’t try to be Mr.
The VI Version is balanced and matched, per datasheet specification, this is highest quality. All from the same factory code. Note that the newElectro-Harmonix A is now available,and it does not requireany rewiring to use.
TESLA is even a frame grid tube!
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”. This is not normal for E88CC, test values can vary widely, and you have to take them as is. May seem a silly advice, but it is a popular mistake.
They are waiting for you there. For a true happened story, read the world of NOS.
So you take samples, you overload them for a certain time, and when too many fail the whole lot is rejected. Interesting detail with satenblatt tube box. Called Uf Test with Voltmeter between Pin 4 and 5.
Try searching the Tube Data Sheet Locatorthe world’s biggest eecc88 of tube datasheets. This was told to me by a retired Telefunken Ulm Employee, so I think this is very reliable information. Please note with some not with all the print text has suffered somewhat from storage.
High Quality tubes from the Prague factory Code Large dimension ECC88, with higher dissipation. Strangely so, but I see it over and over again. This is the reason why JAN tested tubes are so often agvailable as commercial tubes also!! Resistance Coupled Amplifier Charts: Is your ECC88 microphonic? JAN Testing is a military proces for lot qualification, which makes sure that weak production series will not pass as a whole.
Some more useful info: To give you an idea, the size of a large bacteria is 5um. This is a much improverd version of ECC88 made, with efc88 voltage capabilities, higher plate dissipagtion, and better in many many ways. These were made for the military, as you can see from the sword signs on the back side of the tube. All tube data datenblxtt is, including gain, Gm, Plate impedance, grid leakage, etc, datennlatt compare it against “must be” values.
This is a very critical one, and can cause a good tube to get defective, or give hum, sparks or other noise, when exceeded. Only do these measurements inside your amplifier, when you have experience with this. NOS original box Order nr for a matched and balanced pair: This is confirmed by the construction, there is the characteristical A-Shaped getter holder inside, and more details. Left tube on the picture. Used, but look and test like new.
