Head amp input transistors (2SK170+bipolar)
The wretched CMOS audio switch (muting and EQ), which is the subject of so much modding. Here it's factory original
Headphone muting relay. Really an overkill. They already have one muting switch upstream, just after the head amp
Replay head wire and socket
Double Dolby board with four HA12058 ICs.
Recording channel board. Too many DACs to comprehend, but Mr. Ludwig the designer should have known it better than me.
Keyboard wires
