wow, an Intro section !

[Elkaid]

Hello everyone !
An introduction section, quite a good idea !

My name's Emmanuel and I come from Quebec, Canada.

I'm a High Level programmer (Visual C++ etc...) who has been converted to Low Level programming (PIC, 8051, 68HC11 microcontrollers etc...) by my hobby.

Amplifier seems to be every newbie's dream project so mine it is.

I already build succesfully an ECL86 based Preamplifier which I'm very proud of. However, I hope to learn "HOW" it is actually working. I guess reading a schematic is relatively easy but understanding how thing works is a bit more complex

This forum looks like heaven for a guys like me and I hope to learn a lot from you guys.

Have a nice day !

Elkaid,

I already build succesfully an ECL86 based Preamplifier which I'm very proud of.

I missed that sentence the first time I read your introduction.
Welcome to the forum.

Cheers,

 

[Elkaid]

Thanks !

I hope to be of any help in a way or another !

Yes, hard to understand. 😉

To me, understanding why anyone
should build anything using ECL86
is beyond my understanding.

When it is easy as a cake using modern
Transistors. 😉

Anyway you are very Welcome into this Odd Bunch, Elkaid

Hi Elkaid, and welcome🙂

Don't mind Halo😉


How these things work? Well, I was told in each component there are lots of tiny elves with buckets, and they use the buckets to move magic water around...

This makes perfect sense to me, as I have seen the magic water evaporate when things go wrong, and components get too hot😉

Well.... part of the reason you build an amp is besides just listening to it, to see something you made with your own hands operating just nice and dandy. And a tube amp wipes the floor with a SS amp in this regard. Imagine the voices of angels wafting out of the speakers like a soft warm breeze, while you are sitting in the dark staring into the power tubes and looking at the inside of the anode and seeing that soft blue glow, while you imagine those invisible electrons crossing the space you can actually see, the density of them being modulated at an audio rate and actually turning into music. Ahhhh.. smell the warm transformer varnish. Savour the aesthetic ecstasy and symmetry of that transformer coupled push pull output stage. Wood, brass, copper, iron, porcelain, mica, bakelite... Oh, be still my beating heart... 😉

I wax poetic.

 

[Elkaid]

Hehehehe !!!

Thanks again guys 🙂

With the days passing, I guess that I'll become gradually as odd as you all 🙂
Also, I'll read on that "voodoo" cult which seems pretty appealing 🙂

A nice day to you all

It might take a while but you'll get there.😀

 

[Elkaid]

A little time to be become as odd as you...
A very long time to become as good as you all...

Maybe that's why teamworks exist !

Finally, This GainClone thing has inspired me a lot. Should I begin with the "standard" schematic or should I use the "inverted" one ? Any advantages to do that ? (I'm going to read all posts concerning that but there are a bunch of them !)

I've also a TDA7294 project to finish

My thread

In which I will replace the TDA7294 by TDA7293 because I was stupid enough to buy a 2 X 30V transfomer instead of a 2 X 25 by example.

However, there's this tip of adding some windings to the toroidal transformer to decrease voltage that I must try

1st Welcome 🙂

I come from Quebec, Canada.

Quebec the city?

I'd like to see that schematic. ECL86 is usually used to build little power-amps.

who can argue with that?
but that is the trouble with tubes:

you ca not use them for HiFi and Good figures = hard plain facts
you have to get into feelings and and magic and
a mumbo jumbo land of snakes and impressions
to the right and to the left

A true ability in self suggestiveness and mind persuasiveness
will surely help

/halo - still somewhat more scientific
------------------------------------------------

ECL86 - of course I have had my mind to build "a little power amp",
to use planet10's words, with that tube

Nice and cheap, both triode and output tube in one and same package.
Just for to satisfy my own lust in creative work
and for to see that cosy GLOW of the TUBE

😉 Quite tempting, I must say! 😉

 

[Elkaid]

There you go !
Schematic for the "famous", "strange", "odd" and "useless" 🙂 ECL86 preamp

ECL86 Preamp thread

At the bottom, you can see my prototype. I'm not very experienced but it seems to be quite powerful for a preamp !

 

[JoeBob]

Nice to see another quebecer on this forum. As for halo, I couldn't dissagree more, tubes can sound outstanding, not better then SS, but different. I use a mix of the two throughout my system.

And I can bet on you ending up as "odd" as the rest of us...

As for if you want to try your own with a gainclone I'd reccomend the inverted design.

Hope you have a good time on these forums.

Crikey, Circlotron, what substances have you been ingesting?

For me, it's the glow. Turn down the lights and up surface the primitive instincts of feeling warm and safe with a glowing fire to look at.

Fortunately, Emmanuel, there are saner people on the Tube forum (it's just that they haven't posted recently).

hehhe thanks ! I was wondering....

That's the main reason why I tried my hands on the "useless" 🙂ECL86 preamplifier. I also wanted to hear how tubes sounded like.

Have a nice day !

Hi Elkaid,

Nice to have you here 🙂

Halo should maybe listen to more beautiful valves instead of 🤐 transistors 😀: 😀: 😉
