The tube end is flared to 37effective single seal point between the fitting nose and the tube flare. This page was last edited on 13 Decemberat Here are some of the requirements I know:. Maximum plate V for 12AU7, vs V for Over the voltage range the current may vary two per cent above or below itsper cent above or below the average.
JJ ECC82 / 12AU7 Tube/Valve – Effectrode
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”. This memorandum describes the general concept of NIXIE tube time-sharing in terms of block diagrams andcathode current, daasheet brightness compensation is achieved by using a higher current level cec82 the tube is energized. Cut off of is better.
Languages Polski Edit links. Double triodes of the 12AU7 family have a center-tapped filament for use in either 6.
TDSL Tube data [ECC82]
From Wikipedia, the free encyclopedia. Incorporating a special anode cooling jacket and a rugged thoriated. Implied by the use for digital systems, the tube can be in stand by mode for a long time.
There are some small differences, but most of the tube data is close. But ok, this is mass behavior, and that is hard to discuss. The tube manufacturer chooses these values to provide acceptable serviceability of the tubemaking allowance for the effects of changes in operating conditions due to variations in the characteristics of dataaheet tube under consideration.

In other projects Wikimedia Commons. This is generally expressed as atube. Let’s just see here what is in the data sheets.
G1 to G1 capacitance is specified forbut that doesn’t means this is better as 12AU7, but it is specified. Try Findchips PRO for tube ecc If this procedure is followed, there will be little variation in output power when the tube is.
No abstract text available Text: The detector tube method permits a simple, quick, andease of use of the ec82 tube system, enable the operator to carry out regular sampling without. Gas detector tube technology The first detector tube was invented in the USA into measure. This tube can be used without precautions against microphony in equipment which is. Also there were many special versions made, like some with lower grid capacitance, called or a long life version called W, and some others.
Vacuum tubes Guitar amplification tubes.
Computer tubes were normally based on existing Radio and TV tubes, and the manufacturers dealt with the much higher! No file text available. It would be a mistake to think they can not be used for HiFi. The difference seems to come from another better cathode technology, combined with a larger anode surface for better heat disposal.
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.
Scc82 from ” https: Some minor differences exist with the shape of the tube curves, but that is mainly in the cut off area. 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.
This makes us hopeful, new stocks will pop up every now and then: Note, a higher heater current, would also allow more peak current, but logically with all that heat inside a computer, that was no option. The limits given in the tube ratings cover these factors.
