HI Jim!
Thanks for the answer. Yes, you right, it’s a big job but fun for me is something like an hobby. A good chance to do some experiment. The first thing I wanna do is to install IC socket on all circuit board so I can swap from NE5532 to other op amp ( maybe OPA2134/OPA2132 ? And sparkos on output). There is also some suspicious axial condenser on the filter, 600-6K and 2k-20k boards who look like axial multilayer ceramic capacitor
I want to replace them with something better (polypropylene or silver mica maybe?)
What do you think about it?
