Well.... the way i love amplifiers and electronics

turn me very tollerant i think.

I love all those things you posted.... nothing is really ugly into my point of view.

I feel happy..... i feel good that exists so many folks that loves those things alike i love.... this seems to me i have found a lot of lost brothers around the globe... all them saying the same word while smilling;

- "transistors..oh yeah!"

Congratulations... all them lovely jobs.... pretty to me.... ugly to you.

regards,

Carlos

Hi

This is the latest prototype of the amp from post 220. This one works better than the last, mostly due to better layout. It certainly qualifies for the "UGLY Looking Amp! - but good working" contest. This may actually be the last prototype for this circuit as a PCB is now in the works🙂. The looks of this circuit doesn't even come close to defining how it sounds. Very straight, fast and accurate, no coloration, very clear sound stage, exceptionally low noise. It has a measured phase shift from input to output of 200nS with the load attached. Not bad for a non GNFB amp.🙂 Sure it’s ugly, but now comes the challenge to make it beautiful.


Here is more on this amp.

Hello CBS240.

Interesting amp.

Where did you find 'ISKRA' yellow capacitor?
I am just curious.

Hi Mitch,

Those were salvaged from some old electronic junk. (I can be a real skin flint sometimes😀 ) They're 1uF Polypropelyne I used for the input caps. Polypropelyne doesn't exibit the absorbtion distortion that electrolytics, Mylar, or just about any other cap does except Polystyrene or maybe paper & oil (impractical). There is a +input and -input cap, as the circuit can be driven by a balanced line input as well, but these are the only caps in the signal path. I sourced a similar cap from Mouser at $4 - $5 each.

Is there a better source/quality 1uf Polypropelyne cap out there that is suitable for the input cap?? I only have a 2 more....

...also a little bit ugly - my lovely class D learning proto:
But pleasing my ears since two weeks...
And showing respectable distorsions :

Hi, all Friends, and all the others, too.

Here a new contribution to this my own thread.
See my attachment picture.
It is my own construction Class A Single End stereo headphone amp.
It is Ugly .. but sure CAN SING .. some music 🙂
( There is a topic with schematics and description, if anyone intersted )

More of the DIY everyday reality!

I could bet on that the amps that SOUNDS best
built by diyaudio members, are not very exceptionally looking....

/lineup - has only built crappy looking amps

(Moderators:
Any GOOD loooking Amp in this thread should go directly to TEXAS! )

Hi Lineup

No offense, but that circuit really isn't very ugly looking....😀

My GainClone. Being its mother, I think it's beautiful 😉
Care to guess what the base is?

Still bit Ugly, Nigel.
But you will assembly nicely into a chassi, I understand.

I have put it in a flat desktop PC case so I can sit my mixer on top.
I like the PC cases as they have fan mountings built in and are good solid boxes.




Heres one thats not so ugly !

 

[destroyer X]

Ahahahha....i love this thread...the best into whole forum

This construction seems to me that is saying to the ones are watching it:

" Do not seat over here please "...is wonderfull and very funny.

It is not ugly...but it is funny.

"The hot sitting style"
