Amplifier ultralinear used 6P3S

[Adrian Biruescu]

Hopefully, the amplifiers that you're building are more functional than the schematic above and maybe it's time to draw a more readable schematic, using modern software.

Schema corectată nu a devenit pe deplin funcțională de moment. Mai necesită o corecție vizibilă în imaginea de mai jos.

Dear friends I am an honest and loyal person, please do not write heavy things as I do not like poisonous attacks, unfortunately in the modifications of the valves sometimes I do not carry the correct scheme, also because I have not had the time to devote myself fully to complete the scheme using one of my simulation programs, I don't have much time I do a particular electronic job !! Below you will find the link of the diagram and also the photo of how it was when I made it the first time (20 years ago !!) before modifying it

You will also find photos of the preamplifier and one of the loudspeakers, I repeat I ask for education and courtesy, I am a professional and I have been working in electronics for the loaf for over 45 years !! I entered this forum to be in company with you when I have time, I'm not going to sell anything I don't need money !! If anyone thinks that I am a person who seeks the fight they are wrong, I am very sociable and loyal, I work mainly on ultra-sophisticated laser machines post the lnk of one of my films about my work. Greetings

Hello dear friend; no, i'm real and everything i publish is real and working for years, including the changes, i apologize for my distractions on the schematics, i try to publish them complete, thanks again to all of you !!

 Hello; you can still create a similar circuit and modify it, to see the effects, now post a photo of the amplifier in question, thanks to you too

Vezi ca ai gresit, iar, amplificatorul. Nu ne tratam pielea cu laser aici, banuiesc ca incerci sa faci bani din vizionari.

Hello; they are more real and functional than any software treated without knowledge and this is told by u dear friend of Ted Hammond and Harvey Gizmo Rosenberg or meta Gizmo !! Thanks for your advice at the moment of the forms project for laser machines !! Thank you, you're so kind.

you can also find the Stargate 6v6 push pull amp sold about a year ago! The owner is thrilled! Paid at an honest and well made price, good sounding etc ... As you can see my software works !! Greetings!!

if you give me a link I'll make you a check !! What can I tell you, I'm not interested in money and that's it !!

Valid for all; I'm not interested in trading anything, I'm here to have fun with you, there is no profit and nobody has to give me anything, I have enough money to live two whole lives for one hundred and fifty years each !! So zero profit !! Only demonstration of my work for the purpose of curiosity !! my project center is located in Běijīng beijing and the other audio design center is located in bogor where I make mosfet amplifiers !! Hi good evening

hi; It must be admitted that my tim and I know the software, and so also the electronics, even the obsolete ones like the tubes !! Nothing special !! I repeat; I don't need anything, I don't need money, I don't need customers and I deal with foreign business both in the electro-medical field and in the audio field !! So I don't need anything, not even underline what I post for the purpose of curiosity !!

these are part of my projects !! I'm not someone who connects ethernet wires and then believes himself to be God !! I am real and I don't need anything !! I repeat no profit or means ends !! I am not interested in advertising, and if someone wants to show off their skills as a programmer or connoisseur of electronic design software, I can always make sure that they have an outlet by comparing themselves with me and the engineers of my team !! Thanks again to all very sociable and kind and if you think ot see it only as a pure demonstration of my current work thank you !!

Nu simt nevoia să modific/experimentez circuitul defazorului de maniera prezentată în schema dumneavoastră. Motiv simplu, circuitul defazor devine total nefuncțional.

Dacă va uitați cu atenție la ce ați prezentat puteți remarca ne-funcționalitatea circuitului defazor (având în vedere experienta invocată 45 de ani în domeniu).

Ca să înlesnesc înțelegerea dumneavoastră întreb:

De unde sunt polarizate grilele de comandă ale dublei triode 6N7 ? din eter... ?

Așadar defazorul prezentat de dumneavoastră necesită  cuplaj galvanic la anodul etajului din intrare. Trebuie înlocuit cuplajul capacitiv C5 cu un cuplaj galvanic.

6j5 wa tube preamplifier (perfectly silent) 6N7 phase splitter pilot inverter so it looks like a small final power stage able to correctly driver the four 6P3S !!

 

 

Arată dar nu funcționează de maniera descrisă (se pot citi lejer valorile rezistive din etajul defazor..., evident exclud cuplajul capacitiv C5 greșit).

Pentru curenții anodici din etajul defazor 6N7 nu putem defini așa a small power stage .

Aveți idee cam ce curenți la anod apar în schema asta echipată cu  6N7 ?

 

[THOMAS]

Este o schema in mare parte (!!!) gresita,corect nu va functiona niciodata,pe langa cele remarcate de colegul Hoffmann in jurul defazorului,as intreba unde sunt rezistentele de "descarcare" a grilelor de comanda (G1) ale tuburilor finale.....??...sa nu mai spun de cuplajele (valorile condensatoarelor de cuplaj) alese cu totul airea,parca sunt puse din burta!!!

   Postez schema CORECTA a defazorului pentru o functionare cu adevarat buna asta ca sa nu ramana o schema pe care cineva sa o ia de buna si sa investeasca degeaba!!

 

Trebuie sa mentionez ca se poate obtine o putere de 75W...80W cu 4X6P3S in PPP,bineinteles in clasa AB2 si nu cu acest defazor.

so believe and do not research !

 

P.S. I don't care if you simulated thousands and thousands of schematics, it's clear that you do not have the knowledge if you fail to make a wrong schematic to work !
