To give you an idea, the size of a large bacteria is 5um. Even with top-name amplifier manufacturers we see the same old errors, resulting from arrogancy, like not reading a datasheet.
TDSL Tube data [ECC88]
Low noise version of 6N1P. Click Here for sheeton Sovtek 6B4-G. High Quality tubes from the Prague factory Code EHX new production under the microscope. When you refer to finest datwnblatt details, they say they don’t need to know, they have already “30 years experience”. They are waiting for you there. Now that EI is closed sinceprices of EI tubes are expected to soar. Now of course manufacturers could still sell such tubes on the commercial market, but the military refused to take those.
Buy only from reliable sources! These come with Amplitrex computer test report. Note ifyou already have an RCA tube manual, and if the tubeslisted on the RCA charts in the back are same as here, the pageswill be the same as what you already have. Like this, and no other way! Don’t trust it when a sellers offers those repeatedly for low prices. Printing is fainted, but unburned, very white still. Mind you they draw twice the heater current.
Some tubes from equipment are sometimes actually never used. What is best, we had a small lot, and we have been able to select them all in perfectly balanced and matched pairs. This pair has printed on the glass: If you don’t know the answer Left tube on the picture. This is a very critical one, and can cause a good tube to get defective, or give hum, sparks or other noise, when exceeded.
This may help you more than changing tubes. Assessment of The Microwave Tube Industryan inside datenbkatt at ec88 high-tech tubes are used for, why they’re used instead of transistors, what’s in them lots of beryllium! This is probably the best ECC88 ever made. This tube excist as normal grid tube and as frame grid tube.
Other pages online with tube data: Frame grid wires can be as thin as 10um, which is technologically speaking a masterpiece of fine mechanics. Sovtek 6B4-G and 2A3 are slightlydifferent. Perfect quality, good boxes. HQ tubes made for the Czech post, from the Rosnov factory Code The next three boxes are a short overview of the most important thing to check, in case of a problem. This is a much improverd version of ECC88 made, with higher voltage capabilities, higher plate dissipagtion, and better in many many ways.
Leave it up to a technician otherwise. We have Money-back guarantee on those.
Order nr for a matched and balanced pair: So if you order for evc88 tube 4 from this list, it is pre-matched with tube 8. However they bias not as trhey shouls in all circuits, and have slightly lower gain. Please note with some not with all the print text has suffered somewhat from storage.
The 6DJ8 / ECC88 / Tube
This is not normal for E88CC, test values can vary widely, and you have to take them as is. So you think you buy NOS, but they’re not. Iggy Pop’sRussian Tube Reference page. Meaning they are EI tubes. For the rest every little detail is identical. What to do, and why you shouldn’t panic. Called Uf Test with Voltmeter between Pin 4 and 5.
Check also next item, below here. Lucky on internet auction sites. The VI Version is balanced and matched, per datasheet specification, this is highest quality. This chart shows an example of how toset up voltage-amplifyingpentodes for maximum voltage output as opposed to maximum gain The example givenis an RCA Please note that these are OEM spec sheets,except for some of the Resistance Coupled Amplifier charts, you will not be downloading any pages of a regular tube manual that you already have.
Here is a Link to all test reports. They test all at 15mA, with grid voltage variation of less than 0,2 Volt!! The “Help,My Amp has ‘s! Everything you want to know about how tube specsare determined, from flywheel ecd88 testing to altitude testing to salt spraycorrosion resistance.
In many problem cases, the ECC88 is not used correct.
