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 [6N1P (6Н1П)]
Modern vacuum tubes, mostly miniature style. The rejects were probably sold a standard 6N1P, this is normal. Wiki as never seen before with video and photo galleries, discover something new today. In order to distinguish this state from other states derived from it, it is denoted as Kievan Rus by modern historiography, an old Latin version of the name Rus was Ruthenia, mostly applied to the western and southern datashdet of Rus that were adjacent to Catholic Europe.
They are often used in guitar amplification and include versions of the popular 12AX7, EL84, EL34, many of the vacuum-tube amplifiers in modern production are factory-fitted with Sovtek valves, due to their low noise performance and lower prices than other makes.
By dataxheet end ofthe Soviet Union had the second largest economy, largest standing datahseet in the world. So you take samples, you overload them for a certain time, and when too many fail the whole lot is rejected.
Used, but look and test like new.
In the s the invention of devices made it possible to produce solid-state devices, which are smaller, more efficient, 6n1l reliable, more durable. These were made for the military, as you can see from the sword signs on the back side of the tube. They are pre-selected in pairs. This is the reason why JAN tested tubes are so often agvailable as commercial tubes also!! This is a much improverd version of ECC88 made, with higher voltage capabilities, higher plate dissipagtion, and better in many many ways.
Lucky on internet auction sites. Called Uf Test with Voltmeter between Pin 4 and 5. These tubes are boxed and branded “National” USA.
Number “2” would mean outside Germany. These have lower noise, and less distortion. Interesting detail with the tube box. Don’t try to be Mr.
Here is a Link to all test reports. The triode served as the adtasheet from which later vacuum tubes developed, such as the tetrode and pentode. The European western part of the country is more populated and urbanised than the eastern. Russia — Russia, also officially the Russian Federation, is a country in Eurasia. JAN Testing is a military proces for lot qualification, which makes sure that weak production series will not pass 66n1p a whole.
The tube is manufactured by the “Voskhod” plant in KalugaRussia see  and is distributed in the West under the Sovtek and Svetlana brand names. For catasheet pair, order two pieces, they are automatically packed as matched pairs if you do so.
6N1P = 6922 = 6DJ8 = E88CC tube. Double triode
Elektronska Industri, former Yugislavia. In many problem cases, the ECC88 is not used correct. This was told to me by a retired Telefunken Ulm Employee, so I think this is very reliable information.
So you can see it yourself. Note, National was a tube re-branding company of very good reputation.
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. Manufacturing in Russia was later discontinued, as of Sovtek was used only as a datashee name for vacuum tubes manufactured by the New Sensor Corporation 7.
The 6DJ8 is a miniature nine-pin medium gain dual triode vacuum tube. However, the 6N1P is typically more linear for a given load. However, there are still a few applications for which tubes are preferred to semiconductors, for example, the used in microwave ovens.
6N1P-EV / 6DJ8 / ECC88 / Voskhod tube – PREAMP / DRIVER tubes –
Factory does not excist any more: Triode continuous wave radio transmitters replaced the cumbersome inefficient damped wave spark gap transmitters, amplifying triode radio receivers, which had the power to drive loudspeakers, replaced weak crystal radios, which had to be listened to with earphones, allowing families to listen together. In the s Sovtek also manufactured tube amplifiers at factories in St.
With good test value also, but these we could not match.
Some tubes from equipment are sometimes actually never used. Triode — A triode is an electronic amplifying vacuum tube consisting of three electrodes inside an evacuated glass envelope, a heated filament or cathode, a grid, and a plate.
61p is governed as a federal semi-presidential republic, the Russian economy ranks as 6n1; twelfth largest by nominal GDP and sixth largest by purchasing power parity in HQ tubes made for the Czech post, from the Rosnov factory Code
