Default UGLY Looking Amp! - but good working

More pictures of Normal Ugly (but good) AMPS!
PLEASE post a picture of your NOT so well looking AMP!


---------------------------------------------------------
Of natural causes, it is only the most "beautiful amps"
that get pictures posted. They are running the SHOW.
But surely they are only "the tip of an iceberg".

95% of All Good Great Sounding DIY-amps are REALLY Ugly.
Made up of materials recycled from scrapyards.
And simple chassis of thin, 1-2 mm Aluminium.
No fancy LEDs or Knobs.
---------------------------------------------------------

I want to see more of these AMPS.
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

============================================



Just in case you forgot the topic
This was my declaration when I started it .. way back
Sure had no idea it would be popular by normal members
.. only had my little hope
/the same

Default Lineup ugly _ Class A amplifier



This one is not exactly pretty
Picture was taken during testing and trimming days

- Class A
- Separate discrete Lineup Tracking dual Regulator psu for The voltage amplifier
- Output stage has got its own, bigger, Transformer
- Two extra 'added' electrolytics capas to improve ripple rejection

Image ..
is a bit overexposed .. too much light
but I think you all can get how this amplifer works
Sweet and good at Class A around max 4-5 watts out
At least in my speakers ( SPL= 92dB )

Enjoy!

Beauty is in the eye of the beholder.

So, a tribute to my first DIY Amp:

It will be disassembled for next prototypes.

2SA1105 in a MT200 package, with a Toshiba logo ?
When it should be TOP3, with an SK marking.

At least they have a sense of humor.

Above are new, this one is old.
