Even with top-name amplifier manufacturers we see the same old errors, resulting from arrogancy, like dateblatt reading a datasheet.
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.
Interesting detail with the tube box. The negative result is, end users have to swap tubes all of the time, and desparately try to draw conclusions from this. HQ tubes made for the Czech post, from the Rosnov factory Code Mind you they draw twice the heater current. This is a jewel. The frame grid wire is so thin, when you open up a defective tube, you can not see it with the bare eye. Well, I think experience and detailed product knowledge is the same!
These were made for the military, as you can see from the sword signs on the back side of the tube.
This pair has printed on the glass: 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.
Note, National was a tube re-branding company of very good reputation. All from the same factory code. In many problem cases, the ECC88 is not used correct. EHX new production under the datenvlatt.
This one has a lot of pages from the European Philips Tube Manual. 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. All tube data there is, including gain, Gm, Plate impedance, grid leakage, etc, and compare it against “must be” values.
The rejects were probably sold a standard 6N1P, this is normal. These have lower noise, and less distortion.
The 6DJ8 / ECC88 / Tube
This is not normal for E88CC, test values can vary datenblaatt, and you have to take them as is. Large dimension ECC88, with higher dissipation.
Made on Philips machines. Now of course manufacturers could still sell such tubes on the commercial market, but the military refused to take those.
These tubes are boxed and branded “National” USA. Everything you want to know about how tube specsare determined, from flywheel shock testing to altitude testing to salt spraycorrosion resistance.
Used, but look and test like new. So with them, what you pay is what you get. Read below, how to connect the voltmeter.
TDSL Tube data [ECC88]
JAN Testing is a military proces daetnblatt lot qualification, which makes sure that weak production series will not pass datenhlatt a whole. This tube excist as normal grid tube and as frame grid tube. This is confirmed by the construction, there is the characteristical A-Shaped getter holder inside, and more details. Some more useful info: When it writes on there “ECC88, 1 ” as you datenblaht on the picture here this means this tube was made in Germany, indicated by the number “1”.
When frame grid tubes, we write it in the description. Leave it up to a technician otherwise. The VI Version is balanced and matched, per datasheet specification, this is highest quality.
If you don’t know the answer Don’t trust it when a sellers offers those repeatedly for low prices. Assessment fcc88 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! This is a very critical one, and can cause a good tube to get defective, or give hum, sparks or other noise, when exceeded.
