All fine, thanks!
Nice looking opamps, their part number and type extremely easy to read. They're slightly different from 358 opamps I used to , a bit higher power consumption and I had to reconfigure some values a little to make them work properly. I think, there're should be a datasheet that describes those differences. Anyways it is very good stuff that works very well. The delivery took about a month to Kiev (as usual). Very nice store !
