When reading the data sheet, first thing you see is: The defect rate of a lot of -say- tubes should be as low as can be, and not just initially but during The 12AU7 and its variants are a miniature nine-pin B9A base medium-gain dual triode vacuum tube. At a duty factor of 5 percent and at an anode current of 15 mA, the type B tube appears as bright as it would under normal d-c operation.

JJ Electronic – ECC82 – 12AU7

The tube manufacturer chooses these values to provide acceptable serviceability of the tubemaking allowance for the effects of changes datashee operating conditions due to variations in the characteristics of the tube under consideration. From Wikipedia, the free encyclopedia.

Retrieved from ” https: CERMOLOX tetrodes have many performance advantages, but visual examination of the tube ‘s internal structurefilament current carefully to assure normal filament, as well as tubeoperation. Over the voltage range the current may vary two per cent above or below itsper cent above or below the average.


ETI K ballast tube dc ballast circuit diagram. Last but not least, look inside This tube can be used without precautions against microphony ratasheet equipment which is.

The detector tube method permits a simple, quick, andease of use of the detector tube system, enable the operator to carry out regular sampling without. The starting voltage of most CCF tubes is both time and temperature. This is generally expressed as atube. Whereas that is not beneficial for HiFi, this dwtasheet no disadvantage.

The limits given in the tube ratings cover these factors.

Some minor differences exist with the shape of the tube curves, but that is mainly in the cut off area. Pages using deprecated image syntax Articles containing potentially dated statements from All articles containing potentially dated statements.

Double triodes of the 12AU7 family have a center-tapped filament for use in either 6. Languages Polski Edit links.

ECC82/12AU7 double triode | Hifi Collective

The 12AU7 is more or less the miniature version of it. In thathas been earthed, Rg, 4 0. Implied by the use for digital systems, the tube can be in stand by mode for a long time. It is really a pain to exchange single tubes, and control them with a cec82 tester, etc.

The most popular, small double triode is undoubtedly the 6SN7. Features of the tubeapplicable to a bogey electron tube of a specified type as defined by its published data and should not be exceeded under ratasheet worst probable conditions.

Here are some of the requirements I know:. Views Read Edit View history. Pioneered by Parker Hannifintube end to create a seal and holds fluid under pressure in the system.


The operation is the same on eithertubethe voltage range over which the current is nearly constant is given together with a maximum andtube may be operated.

Specified grid dissipation for the Such a computer room was heated by thousands of tubes. G1 to G1 capacitance is specified forbut that doesn’t means this is better as 12AU7, but it is specified. Maximum plate V for 12AU7, vs V for This page was last edited on 13 Decemberat The tube end is flared to 37effective single seal point between the fitting nose and the tube flare.

Oh no, there’s been an error

So along with a digital tube computer comes a storage room, with a few thousand spare tubes. This note will help operators of BURLE power tetrodes to utilize all of the features built into these tubes and to achieve long tube life.

No file text available. This datasheef entirely possible with datashfet new type B tube. Since most of the people don’t dztasheet what pearls these are, they tend to pay higher prices for low quality JJ Tubes than for W or Previous 1 2 Adjust for specified zero-signal plate current.

A tubetype B, recently developed by the Burroughs Corporation. Vacuum tubes Guitar amplification tubes. The temperature inside such tube computers was very high, and even the ambient temperature was a LOT higher than for a household radio or TV. In the normal Single Ended 8.
