I am approaching the end of the project. This 1060 phono preamp sounded phenomenal even with the old caps.
I started to replace the resistors and electrolytic, the plan is to replace it all and the tantalum too. As on the other boards the original films and polystyrene capacitors will stay.
As I learned here, the original green Nissei films are good sounding and the polystyrene capacitors last forever, have low distortion and tight tolerances.
The transistors 2SC458 will be replaced with KSC1846 type. I have to do this later, I need a transistor tester to be able to match transistors gain for left and right channel before I get to it, there are no diodes on this version.
I have to say that this board was somewhat tricky, it different from service manual and required extra attention...
