This CD Player seems to be one of the most popular made in China. The  extensive modification below aims to exploit  all its  hidden capabilities.

Modification parts used :

 1) 5 of 1uF 100V Aerovox for coupling and heater bypass

2) 2 of 0.1uF 160V for line board inside coupling

3) 2 of 350V/uS slew rate AD826 op amps  

4) 1 big 1uF 220VAC Aerovox for High Voltage (HV) bypass

5) 1 of 0.1uF 200V Teflon cap for digital PS bypassing

6) 4 of 0.1uF 200V Micamold for bypassing HV, digital and  

    analog PS

8) 4 of 200V 3A FRED EGP30D diodes for analog PS

9) 1 Panasonic 100uF 250V for HV PS

10) 1 of 7815BT 15V regulator paralleled  to beef up the 15V

      op amp rail

11) 4 of DIL AD825 replacing the NE5532 and AD2604

Should you wish to mod yours, feel free to contact me ; I might be able to share some of my experiences.

This is a famous UK vintage CD Player with a exceptional sound.

As modification is rather difficult due to its limited space and parts are tightly soldered on its PCB , I done only change of  capacitors with paper in oil type caps.
