TELEFUNKEN ECC803

LS50 - the grandmother of all modern power tubes, introduced in 1938 the first 40/50W power pentode, most famous use was inside the V2 rocket as the control device of the directional flaps. Still made today in Russia and China in slightly modified form.

The info about EL84 is not quite correct.

EL84 was invented by Mullard and copied by TFK.

Best Tubes made by Telefunken

Telefunken developed, manufactured and distributed vacuum tubes from 1910 to 1980. During that time Telefunken laid the foundation of tube design and material science for nearly all other companies to follow; even today the impact is still visible with the few remaining manufactures left.
The picture above shows the milestones of modern tube development and even most of those tubes are not known to the average tube enthusiast, all those tubes are masterpieces of vacuum design, all of them were developed and build by the historic Telefunken company.

From the left to the right:

LS50 the grandmother of all modern power tubes, introduced in 1938 the first 40/50W power pentode, most famous use was inside the V2 rocket as the control device of the directional flaps. Still made today in Russia and China in slightly modified form.

EL151 short lived 60W pentode that was developed at the end of the war to replace the LS50, build only in small quantities to 1960.

EL152/FL152 the post war version of the LS50 introduced in 1947.

EL84 the most famous Telefunken developed tube ever, copied by nearly every tube manufacture in world and is still made today in various forms.

EL156 a simplified version of the EL151, most famous for the use in the Telefunken V101 poweramp and with 50W plate dissipation the most powerful standard production audio tube ever made. The last tube type that ran of the production line in Ulm in 1980. Still made in modified form in China.

EL3010 The most advanced power tube ever made, designed to use with transistor drivers, like most Telefunken tubes original developed as a radio transmitting tube. Due to the high price it never found the way into audio designs.

YL1350 the last developed tube by Telefunken and with 70W plate dissipation the most powerful audio tube ever developed. Original designed for Dynacord in Germany, when they tried to come up with a bassamp to compete against the SVT on the American market. Before the tube went into production the plug was pulled and only the first 600 pre production tubes were ever made.

Nice Telefunken EL84 tubes.

I am using Telefunken SS preamp; tuner and power amp too. Very sweet and dynamic with good details.

i like the AD, thanks akaigx!

tim,

telefunken V69 is good but there are only few on earth that work properly.

without the proper preamps like the v72/v76, one simply cannot bring the best out of it;-)

大陸的光頭一般價錢都是三幾拾。有人賣到二三百。搶錢！

當幫我宣傳, 幾好

254mm hing 我唔識佢亦冇興趣識, 我只知有２個朋友幫佢買頭, 真係賣大６頭,價錢係外面double! 有D人費事出去揾,一百幾拾唸住咪算囉,點知買完先知苯實!不過冇問題,一買一賣你情我願,但奉勸大家先check check價!

akaigx兄，我吾識254mm亦未見過佢，不過係R33係人都知佢高價賣d劣質大陸制造鐳射光頭俾人，又話自已係換光頭C-Fu，但係什麽是CD伺服線路，什麽是Laser head tracking完全吾識，又扮自已好識英文咁，又鬧人吾識電腦吾識英文無用，完全係254mm自已生得五短身形，心理自卑而產生出來的精神抑鬱病態。我吾會怪佢，不過希望佢盡快揾心理醫生幫吓佢。

OK thanks for your advice, I will take it, just to alert other people. Sorry again to Akaigx

254 mm hing, I understand your feeling. But I think it is already nough, when you mentioned the events of cheating such as "賣爆邊喇叭俾網友". I can feeling what you have seen before.

I must say sorry to you, akaigx, but this guy really sucks. Always trying to cheat web-friends. A Hi-Fi 友 but with evil heart.

我開這個主題係因為看過,用過Telefunken膽及機的威力,加上在YOU TUBE那個Telefunken膽廣告,令我想表揚昔日Telefunken的偉大成就,令更多人知道Telefunken的優點,各位R33朋友如果以前因為私人交易出了問題而有怨言的,請另開Topic再細心討論吧,請不要在此Topic交手,謝謝!

賣爆邊喇叭俾網友, 俾網友踢爆, 唯有回水, 你創先

Kakkakakakakakka, 你呃人呃夠未??

賠錢俾人你創先河
