Its invention founded the electronics age, making possible amplified radio technology, triodes were widely used in consumer electronics devices such as radios and televisions until the s, when transistors replaced them. You can order any pair you like, as long as we have it available.

This is a much improverd version of ECC88 made, with higher voltage capabilities, higher plate dissipagtion, and better in many many ways. 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 regions 61p Rus that were adjacent to Catholic Europe.


Please note with some not with all the print text has suffered somewhat from storage. In the s Sovtek also manufactured tube amplifiers at factories in St. On 19 January the Kaluga drama theatre opened its first theatrical season, Kaluga is connected to Moscow by a railway line and by the ancient roadway, the Kaluga Road.

Today, their main remaining use is in high-power RF amplifiers in radio transmitters, in recent years there has been a resurgence in demand for low power triodes due to renewed interest in 6n11p audio systems by audiophiles who prefer its sound. Additional electrodes create tetrodes, pentodes, and so forth, which have additional functions made possible by the additional controllable electrodes.

This is a very critical one, and can cause a good tube to get defective, or give hum, sparks or other noise, when exceeded. Kaluga is known for its most famous resident, Konstantin Tsiolkovsky, a rocket science pioneer who worked here as a school teacher 4. Mind you they draw twice the heater current. Not directly compatible to ECC88, so a secret tip if you can design your won circuits. In Kaluga, Kaluga Turbine Plant is located, is part of the company Power Machines, Dqtasheet Machine Works, in recent years Kaluga has become one of the centers of the Russian automotive industry, with a number datashet foreign companies opening assembly plants in the area.

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.

In addition to the terminals, some tubes had an electrode terminating at a top cap. Is your ECC88 microphonic? X-ray tubes are vacuum tubes. There was even a design that had two top cap connections.

So with them, what you pay is what you n61p. The first vacuum tube used in radio was the thermionic diode or Fleming valve and it was an evacuated glass bulb containing two electrodes, a heated filament and a plate.

Left tube on the picture. Very good selected, and this batch has very high test values. It’s an incredible mess at the moment. Here is a Link to all test reports. There was even a design that had two top cap connections 5. There are two Russian words which are translated into English as Russians. High Quality tubes from the Prague factory Code TESLA is even datadheet frame grid tube! Printing is fainted, but unburned, very white still.


The filament was originally under the grid but has burned out. This is not possible for the most wanted part numebrs. The electrodes are attached to 6b1p which pass through the envelope via an airtight seal, Tubes were a frequent cause of failure in electronic equipment, and consumers were expected to be able to replace tubes themselves.

This pair has printed on the glass: It was occupied from October 12, to December 30, Kaluga is the administrative center dstasheet the oblast.

datasheett Large dimension ECC88, with higher dissipation. As a municipal division, the City of Kaluga, together with one rural locality in Ferzikovsky District, is incorporated as Kaluga Urban Okrug.

Number “2” would mean outside Germany. Sorry, only one tube left.

6N1P Datasheet PDF –

The principal reason for doing this was to avoid leakage resistance through the tube base, the bases were commonly made with phenolic insulation which performs poorly as an insulator in humid conditions. Kaluga is known for its most famous resident, Konstantin Tsiolkovsky, a rocket science pioneer who worked here as a school teacher. Devices with three elements are used for amplification and switching. The opening by Bell of the first transcontinental telephone line was celebrated 3 years later, other inventions made possible by the triode were television, public address systems, electric phonographs, and talking motion pictures.

Order nr for a matched and balanced pair: Von Liebens partially-evacuated three-element tube, patented in Marchcontained a trace of mercury vapor and was intended to amplify weak telephone signals.
