- Pictures here: historische-ele... Tubeamplifier - operates two triodes RV278 (thoriumoxide-cathode), each 50W plate dissipation, 1100Volts. RE604-driver and parafeed circuit. Towards the end you heare the input-choke of the power supply reacting with the variing load, meanwhile the amplifier is connected to a dummy.
I love telefunken! By far the best vintage audio stuff! From the first reel to reel player about mics to mixer and preamps (v72)...all the higesd audio stuff come from germany/austria and with studer frim swis, all 3 german lands! I have studed vintage recording and nothing come close to telefunken, klangfilm, simens, wsw, aeg, studer and all other ...neumann, emt ...all german/Austria ...also abbey road studios have 90% telefunken stuff! Redd was also v72 loaded, redd51 was english preamps ...by far the best studio technic in History! That is it also today! Preamps v72 are so high in price, tapemaschines, u47, emt plate rev., neumann tube vinyl cutter! ...love it!!!!
Very powerful and impressive sounding amp for 1937!! Telefunken made very high quality tube audio systems back in the early days...Friends, Lloyd.
Built to be serviced in the field. A great example of German engineering.
Awesome piece from Telefunken Deutschland
Wow! Thats amazing! I wish I could smell it. Thats sounds strange I know but I love the smell of old vintage amps.
I can feel with you...
I would check those four interstage coupling caps to make sure bias levels are correct.
Dude's monthly electric bill must be gargantuan.
Geiles Gerät, toller Song! Sowas will ich auch
TELE-FUN-KEN damals echte Qualität,heute eine Ramschmarke!
Beautiful
Great sounding!!!!
Pure beauty !
very nice, sorry i write now in German. Absolutes Liebhaberstück. :-)
love to see what speakers your driving please next video perhaps ????????
Love it. 😀
Sensacional!!
Hallo Christoph ,
ein sehr schönes Video was Du hier zeigst .
Nur eine kleine Anmerkung , die von Dir ebenfalls erwähnte
STUDER A 816 basiert meiner Ansicht nach auf der Vorgänger-Maschine A 820.
Ich glaube STUDER hat dann lediglich einige Dinge implementiert.
Wie zum Beispiel den Hebel zur Laufwerksteuerung.
Gruss
Wolfgang
Very good !
Being a 1930s high powered German PA Amp, any chance it may have be used in the nuremberg rallies?
Thank you for share.
Great looking/sounding amp...... Where do you find all this stuff?
Very good 👍👍👍
may i ask about the version of the toccata/fugue ? i like the character of that recording very much. thanks
Top..! Gracias..!!!
I'll be re-tubing that monster would cost a pretty penny.
Thats a killer :D ...to old and to high voltage, heavy stuff to use but Beautyful my friend! ...have you may the v41 Amp? ...im looking for?
very cool amp
TRUELY 5* only a valve amp can sound this good!!!
yardmaster 04357 judged through a digital RUclips stream...
...And most likely played back via an ageing laptop with a Logitech 2.1 system. Though it does raise an interesting point on perception, or an age old point maybe?
LOL, that says more about how you consider good sound than what is actually good. Everything is wrong with that comment: 1. The sound source material is not the greatest for audio testing. 2. The speaker is unknown. 3. The microphone used is likely a crappy phone microphone. 4. RUclips is doing its compression. 5. You probably listened to this MONO sound on your laptop crappy speakers...let me tell you my honest judgement...too poor S/N ratio (noise is very audible), very colored, very distorted and MONO. But, still, it's impressive electronics from long ago. Just don't fool yourself and think it beats a modern well designed amplifier that does hugely better on S/N ratio, distortion and linearity. A tube amp can have more "ear friendly" even order harmonics distortion than a hard clipping transistor amp when you push it hard, but it's hardly an argument if you have adequate power. Besides modern well designed transistor based amps don't hard clip anyway.
am 200-Ohm Ausgang? Welche Lautsprecher betreibst denn daran?
The heaters on the output tubes run pretty hot. How long do those tubes last?
Nice vintage amp, where was it used for?
Nice!!!
maravilhoso
sir, i envy you
@marcelh85 for public address, I think
HI VOLTAGE detected
I've had such a unit, but it was in horrible condition. I have sold it on ebay for something around 1000 Euro.
nice
Дас ист фантастиш !
gooooo~~~d ...!!
Cet ampli a sérieusement besoin d'un réglage! Revoir les condensateurs, et le bias des tubes, cette distorsion est excessive!
ATTENTION!!!! Ne jamais faire fonctionner un ampli à lampes sans HP!!! La surcharge du transformateur de sortie risque de détruire l'ampli de façon irrémédiable!
Le son que vous entendez à la fin de cette vidéo est typique du son d'un transformateur de sortie.
Bien dommage pour cet ampli d'être malmené par l'ignorance de l'usager...
I think the distortion is from the microphone. And where does ge disconnect the speakers?
Running without a load generates very high voltage that can break down transformer winding insulation. I hope the noise is just magnetostriction and not arcing. I would love this amp. I would even manually rewind the transformer to save it if it was damaged. Edit: just looked at the schematic; the resistor and gas discharge tube/lamp going across output tube plates looks like an attempt to suppress high voltage spikes across the output transformer primary. Maybe that has saved it.
typical over engineered quality stuff of the time. They found after the 2nd war the Germans had surprisingly sophisticated equipment. The only things one hears about is the audio and sound reproduction items. They were more then a match for the Japanese if measured in normalized samples. After all most of their technology was conceived by us Jewish folk before the war.
It´s a petty to use this here as platform for generall propaganda!
Surprisingly sophisticated? Holy crap! First there was no surprise and second it was years/decades in advance of the rest of the world in many areas. In fact thanks to the tape machine invented there and taken up by Ampex (thanks to Bing Crosby) the modern superlative fidelity revolution that followed would never have taken place. Your final sentence has no merit or indeed evidence.
PS I am definitely not a right winger - the opposite in fact. But I am an engineer who appreciates the great strides made in Germany in so many areas , high speed flight and aerodynamics, swept wings the first helicopter - this was an unmeasurable time ahead, jet and engine technology, though likely partly pinched from whittle patents, still again in advance of everyone except the British, plastic tape formulation was among the electronic research allowing modern recording techniques and changing the music industry, gave us beautiful music in high fidelity. The rocket motor which changed the face of the world - placing men on the moon. The Mercedes and Auto Union race cars years ahead of everyone else. The Volkswagen. Radar along with the British. The splitting of the atom. Etc..etc...it is endless almost.The sciences, chemistry, physics and unfortunately weapons of war were Nazi priorities. Lastly, they gave us the most powerful lesson in history.
Telefunken was created by Siemens and AEG...how many of us have ever heard of Emil Rathenau (his son Emil was killed by radicals in 1922)?
Small typographical misprint - his son's name was Walther Rathenau.He served as Foreign Minister in the Weimar Republic .
