Hi,

Whilst truffling around the 'web, I came across this company: http://www.conisis.com/english/doa/index.html

After 30 years, I wonder if anyone's seen a complete, authentic schematic?

How much does this link have in common with the op-amp:

??? It looks pretty complete to me. Why is a 3rd party firm selling op-amps for a high price?

Pretty cool, huh?
read JC's thread for his latest thoughts.

Maybe I didn't use the right search term before posting here. You can see a more comprehensive thread on this topic, including some lab analysis, here: http://www.diyaudio.com/forums/showthread.php?threadid=28331&highlight=

That Japanese firm is quite unusual. Take their Neve knock-offs for example; instead of cloning the gear everyone wants, i.e. the discrete stuff - 1066 /73 / 84 etc, they sell clones of the later V1 + V3 modules (not noted for sound quality, George Massenburg made a famous quote about them...not complimentary)... If you copy a '70s design you may get sued, but you can argue the copyright's expired... I'm not so sure about those Pope designs from the '80s...

(The 'V' in Neve's name protocol stands for 'Vatican', a pun on the designer's name, David Pope)

Maybe the Japanese firm should come up with a pun on the ML op-amp designer's name. Answers on a postcard please.
