EL84 TELEFUNKEN PDF

One day, in the middle of work time, a colleague entered my office to ask something and from the corner of my eye I glimpsed a man who was staring like hypnotized into an amplifier. While she was leaving, I called her out to leave the door ajar. The modest man in mid-fifties was turning and gazing like a little kid around a new toy. I went out to get to know him and have a chat. Another tube freak and a new instant friendship. Word by word, and an invitation followed to visit him to review his system and listen to some tracks.

It has a 9 pin Noval base and is found mainly in the final output stages of amplification circuits, most commonly now in guitar amplifiers, but originally in radios and many other devices of the pre-transistor era. It was developed to eliminate the need for a driver tube in radios, and has rather more gain than is usual in a power pentode, producing full output from a relatively small drive signal.

This eliminated the need for a preamplifier triode in radios, making them cheaper to produce. As the EL84 itself is a 9 pin Noval, it was also cheap to produce and manufacturers were quick to adopt it in general use, and they are found in many old European valve radios. It is capable, when used at its plate rating of volts maximum, of producing 17 watts output in Class AB1 in push-pull configuration. Developed by Philips in for use in the British Mullard amplifier, the EL84 came to prominence when used in Watkins and later the Vox amplifiers preferred by many British invasion bands of the s.

When overdriven, the EL84 power tubes in these amplifiers produce a distinctive chiming, articulate, treble-heavy sound when compared to 6L6 tubes more commonly used in American amplifiers of the era such as those from Fender. The watt moderate end pentode was mentioned in the European Telefunken tube catalog.

In the s the EL84 was used in nearly every European class-A table top radio, delivering 5. Manley Stingray.
