I saw NAD 3050 and “retro look” and got all excited thinking someone had an amp from the same eta as my NAD 3150 from the mid 80’s. The 3150 is the second amp I bought in my youth and has been a great amp. I’ve had to replace the output transistors once and the power supply seems to have a problem now (probably electrolytic caps) but the schematic is available online so it shouldn’t be too much trouble to repair. NAD has always been a favorite for me.
