Bought this 13 years old stuff from a goodwill shop for only CAD$9. The outlook of this machine is quite attractive. But what can I expected from it's sound?
Yes, it sound really like the music played behind a heavy curtain, dull and weak.
Opened the case, found the pcb is quite simple and neat. Not too much components, even none a transistor seen there. I wonder the design of this machine might be the desktop version of a portable CD player.
Since I don't know much about digital, so what I dare to do the mod is the op amp and power supply.
Original op amp is LM833 and I want to change it with NE5532 (bipolar) or TL072 (jfet). What will they sound like if I replace it?
Regarding the power supply, do I need to replace the transformer, it look like quite large enough to provide adequate power, isn't it?
The cap, change it with large one? But the cap is ELNA. Will it deteriorate the quality if replaced by other brand?
Hope Masters can give me some guidance to bring the brilliant to this CD player.
Thanks so much for yours help.
