Brakspear sorry you must have been replying at the same time so I didn't see it.

I basically have what you describe apart from the series R from pin 7 to RCA....but having gone straight to new plugs I've omitted the R661/662 path and anything around there I guess

Shall see what tomorrow brings!

Hello,
I have bought a used CD6002 player from Marantz.
I would like to improve its sound.
Any suggested mod for this player that doesn't have OPA ?
Thanks

Things you could try:

a) taking the output before the output caps via e.g. 47R resistor (if the DC offset is within reasonable limits);
Separate the output stage power rails for channels.

b) use DOS output stage;

c) use the filter part of the DOS output stage and feed the signal out via e.g. OPA132/134 or other type of opamp.

d) move the project to the CD6002 thread .
