Smile wow, an Intro section !

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 !

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.

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.

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

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