Bonjour Azazello, Bienvenue sur le forum Audiyofan.

Jolies réalisations ! ! ! !

Salut et bienvenu

Jolie photo sur ta page Pica

Pour ton SE de 6c33c c(est le schéma avec des 6e5 qu'on trouve sur le net
via certain vendeur d'ebay

Peut tu nous en dire plus

Même en anglais, si ça t'est plus facile

Merci! http://www.russiantubes.com/prop.php?t=12&p=369

S=30 ma/v !!
Ra output transf = 1,2 kohm
Bias 6S33S mixed, Rk = 100 ohm, Ia=280 ma, fixed bias=31v.
Ua-k=185v.
U psu = 225v.
Ra 6E5P=8,2 kohm, Rk=62 ohm, Ia=25 ma.

The sound is very clear and amazing!

Thanks for detail

I see on your pica's page the 6C41C amp

Can you tell us more about it

The schématic and measurement if you have

I'm interresting by this design

OK ! Avec plaisir!
Demain je ferais le foto de ma schematic....
J'ai fait se ampl. pour mon ami....avec parleurs Sansui 1700 et CD player Sansui. Great sound!!
Bias 6C41C mixed, U psu=200 v, Rk=100 ohm, Ia=120 ma, fixed bias=-38 v,
Ra output transf.=1,5 kohm, 15 sq. cm. Cathode caps - 1000 ukf/25v Black Gate.
The driver for 6C41C is the same - 6E5P.

Hi Azazello
It would be easier to "speak" english for you, and to understand well for us. But perhaps you would like to practise your french so...
" Bias 6C41C mixed, U psu=200 v, Rk=100 ohm, Ia=120 ma, fixed bias=-38 v"
I think your bias is quite strange -38 V is really low for a grid wich goes up to -220 V.
If do like a tool for your schematic, desselec is free and quite well.

All Bias is 50 v ! /12 v on the res. RK=100ohm!/.
If Uak 6C41C is 183 v /200v - 12v - 5v apr.outp. transf/ Bias -50 v is
enough....The 6C41C are some different....I have a pair 6C41C with bias
74 v for Ia=120 ma.

Yves would tell you that the 2nd grid of the 6E5P would like to be driven by a stabilized alimentation with this for exemple http://www.passion-tube.com/phpBB3/view ... ?f=3&t=255

Je ne peux pas aller.....

you just have to incrit. and so let's go!
And then I guess you want to practise your French...

What do you think about ?
I don't have any experience, but i think this is not real for few arguments.
First of all this tube was designe for military applications, so I guess that during the cold war, you can't stend half an hour to get your material ready...
In the same time, your experience would show that 6s41, would be like an half of 6s33. But the dissipâtions are differents, and the the graphs are also really different. what could you tell about it ?
Then I'm agree in fact with the argument of just one half of tube is better than two, because it can dissipate 45 W per half than 37.5... this is not enormous, but enough to obtain a quite better linearity. and quite the same watts.
I'm also agree with the fact that 6s33 are really "difficult". I've already killed few of them, just for testing http://audiyofan.org/forum/viewtopic.ph ... &start=135
It last here, and begin just before...
I try to play well in PP design and cathode follower end up before transformer... But it does'nt seem easy to do.

What can I tell You...?
I used in my experience 3 math.pair of 6C33C, but there wasn't any problem....u /mu/ is good, S is very good, Ri is very low, perfect linear,
sound is fast and strong. But I lake more 6C41C, temp. stabil. is better,
because there is one anode and I can use more Ia, than from 1 anode of 6C33C.
The sound of 6C41C, I think, is very delicious and clear!
I prefer 1-3 W constructions with min number of parts /Hi-End is inversely proportional to the number of component parts!/ for good sound, like 5687, 6C45P, 6E5P, EL11/in triode mode/, 6C4C, 2A3-RCA/the best my ampl!/,
6F6 /in triode mode/. Sensitivity of my Hornes is 96 db, and it's enough
for my low-watts constructions.
/normally all schematics are only in my head and what kinds of tubes to use
is my decision....sometimes I use only some idea.../

....I don't like PP, because, IMHO, it sounds....cold, metal, when upper and down
tubes are switching.
Mon "amour" est SE cl.A avec sa chaleur!
