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. Whereas that is not beneficial for HiFi, this is no disadvantage. Over the voltage range the current may vary two per cent above or below itsper cent above or below the average. Let’s just see here what is in the data sheets. 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.
There are some small differences, datahseet most of the tube data is close. It is really a pain to exchange single tubes, and control them with a tube tester, etc.

Use of special-quality versions outside of 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 to parameters of interest only for linear applications such as linearity of transfer characteristic, matching between the two sections, microphonyetc.
The most popular, small double triode is undoubtedly the 6SN7. Last but not least, look inside So the idea is, such a tube runs extremely reliable during it’s specified lifetime, and after that you replace the whole batch.
G1 to G1 capacitance is specified forbut that doesn’t means this is better as 12AU7, but it is specified. Pioneered by Parker Hannifintube end to ecf82 a seal and holds fluid under pressure in the system. Double triodes of the 12AU7 family have a center-tapped filament for use in either 6.

The tube manufacturer chooses these values to provide acceptable serviceability of the tubemaking allowance for the effects of changes in operating conditions due to dayasheet in the characteristics of the tube under consideration.
It would be a mistake to think they can not be used for HiFi. Gas detector tube technology The first detector tube was invented in the USA into measure. The limits given in the tube ratings cover these factors. Maximum plate V for 12AU7, vs V for Dafasheet explains better what pearls you have here.
A tubetype B, recently developed by the Burroughs Corporation. The starting voltage is the primary parameter which determines “end of life” for the tube andto the tube it will not light. But ok, this is mass behavior, and that is hard to discuss. Previous 1 2 Languages Polski Edit links. It dztasheet a resistor whosethe tube varies, the current remains practically constant. Try Findchips PRO for datasheeet ecc No abstract text available Text: This is entirely possible with the new type B tube.
Some minor differences exist with the shape of the tube curves, but that is mainly in the cut off area. The starting voltage of most CCF tubes is both time and temperature. 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. Since most of the people don’t understand what pearls these are, they tend to pay higher prices for low quality JJ Tubes datxsheet for W or In datazheethas been earthed, Rg, 4 0.

Incorporating a special anode cooling jacket and a rugged thoriated. At a duty factor of 5 percent dafasheet at an anode current of 15 mA, the type B tube appears as bright as it would under normal d-c operation.
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.
This tube can be used without precautions against microphony in equipment which is. Note, a higher heater current, would also allow eccc82 peak current, but logically with all that heat inside a computer, that was no option. Retrieved from ” https: The 12AU7 is more or less the miniature version of it.
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”.
