That is a watch made for Marie Antoinette. Took 45 years to build from 1782 to 1827 at which point Antoinette had been 34 years dead from the Guillotine. The work was partly done by the original Breguet, and finished by his son after his death. There are currently two of them. The original was stolen, and Breuget (still in business!) made a duplicate, which even with the original drawings took them three years to build. Then the original was recovered - and is currently insured for $30m. One of the most famous watches in existence, and a thing of real beauty - particularly when you consider it was completed nearly two centuries ago.- The Knuckledragger 3rd Memorial Slow Forum Post

Nice looking set up. Quad power amps - don't recognise the deck - a Linn? And what is the pile of stuff behind the left speaker? Sub amp and mains regenerator?- And now what did you do TODAY?
That is awesomer than my anecdote for the night. Went to see Amanda McBroom http://amcbroom.com/ this evening in London. Been listening to her music for decades. I went and said hello afterwards and got a cuddle. Seventh heaven! But McCartney - wow!- Part Sourcing Assistance/Advice Thread
Apart from the 2SK170/LSK170 the lowest noise n-channel FET I've found is the BF862 with 0.8nV/rootHz. This is a 700MHz surface mount device and is made in the bucket load, and is a factor of several cheaper than the LSK170. The key it seems is to chose RF devices in which noise sources with low impedance drive (like an antenna) are important. Difficulty of course is finding complementary devices - the closest are the current offerings from Linear Systems. At least they do the LSK389 - if they eventually produce the LSK109 (they took long enough to crack the LSJ74 fab problem!) that would be nice indeed.- Happy Birthday, Milos (n3rdling)!!!

Analog Devices (actually now TI) just announced the obsolescence of the lowest available noise biplolar parts - pnp matched doubles with a noise of <0.7nV/root Hz and 1/f corner of 3Hz - SSM2220 and MAT3 http://www.analog.com/media/en/PCN/ADI_PDN_16_0034_Rev_-_Form.pdf . The MAT12 is still current, buy eye poppingly expensive in a metal can only. These have a noise equivalent resistance of about 30 ohms. The only thing I know of that used to have lower noise was the late lamented Rohm 2SB737 with <0.4nV/root Hz and <10 ohms equivalent resistance. That was just too damned useful to survive without being discontinued. Lots of fake Chinese stuff out there. Also the On Semi 2N5087 low-ish noise PNP is now obsolete too.
