Dear All those whom have a Marantz Cd 50, I thought I would share some pics for your reference in case you are thinking of modifying it.
The Player has had the following
Audio GD discrete op amps (Earth Variety)
Audio GD clock with discrete power stage
Jantzen Caps(replaced the Obligato's) output capacitors
seperate power supply to the clock(bit of over kill but better to be safe)
No Oversampling mod re- Lukas Fikkus-Lampizator style.
re cap of TDA1541 with metal film decoupling caps
metal film decoupling of power supply regulators
metal film decoupling of Power Filter Capacitors
bitumen lined base and cover
larger supply power caps around discrete op amps
It was certainly a challenge for a novice like me but it was definitely worth every bit of it.
What a great sounding player, highly recommend doing it over the flat uninvolved stock unit.
regards
JP
