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

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!

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.
