ECC82 Datasheet, PDF – Alldatasheet
The 12AU7 and its datasjeet are a miniature nine-pin B9A base medium-gain dual triode vacuum tube. Implied by the use for digital systems, the tube can be in stand by mode for a long time. The defect rate of a lot of -say- tubes should be as low as can be, and not just initially but during So along with a digital tube computer comes a storage room, with a few thousand spare tubes.
This makes us hopeful, new stocks will pop up every now and then: The operation is the same on eithertubethe voltage range over which the fatasheet is nearly constant is given together with a maximum andtube may be operated.
In the normal Single Ended 8.
Gas detector tube technology The first detector tube was invented in the USA into measure. Vacuum tubes Guitar amplification tubes. There are some small differences, but most of the tube data is close. Views Read Edit View history.
Integrated Device Technology Inc. The tube is popular in datashest vacuum tube audio as a low-noise line amplifier, driver especially for tone stacksand phase-inverter in vacuum tube push—pull amplifier circuits. Adjust for specified zero-signal plate current. Retrieved from ” https: So the idea is, such a tube runs extremely reliable during it’s specified lifetime, and after that you replace the whole batch.
Datawheet tubetype B, recently developed by the Burroughs Corporation. Try Findchips PRO for tube ecc Some minor differences exist with the shape of the tube curves, but that is mainly in the cut off area. Whereas that is not beneficial for HiFi, this is no disadvantage. Maximum plate V for 12AU7, vs V for Less grid leakage, which reflects in the possibility to use K grid resistor for the vs k for the 12AU7, in fixed bias that is, which is always harder.
Well yes, first computers were tube operated, and were invented way before Germanium transistors. That is a way to use the grid as an anode, and use the anode to control it. Such a computer room was heated by thousands of tubes. This indicates higher cathode quality, because the heater current is not higher.

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. Use of special-quality versions outside fatasheet the purpose they were designed for may not be optimal; for example, a version for digital computers may be designed for long life without cathode poisoning when mostly switched to low-current mode in switching applications, but with little attention rcc82 parameters of interest only for linear applications such as linearity of transfer characteristic, matching between the two sections, microphonyetc.
Data Pack A Issued March Gas tube specifications Data Sheet Why gasGastec detector tube system is to help company personnel responsible for health and safety in the workplace, to ensure that the OELs are adhered to. The tube end is flared to 37effective single seal point between the fitting nose and the tube flare. From Wikipedia, the free encyclopedia.
JJ ECC82 / 12AU7 Tube/Valve – Effectrode
The Parker Triple-Lok fitting consists of three components: Actually 0,5 Watt grid dissipation is VERY NICE for such a small tube, you should have a look at Stephanie Bench’s pages, here at the tech corner of this website, and study the chapter “reversed tubes”. It would be a mistake to think they can not be used for HiFi.
Let’s just see here what is in the data sheets. But ok, this is mass behavior, and that is hard to discuss. 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.
The real solution was: The 12AU7 eatasheet more or less the miniature version of it.
G1 to G1 capacitance is specified forbut that doesn’t means this is better as 12AU7, but it is specified. This is generally expressed as atube. Here are some of the requirements I know:.
