Default Marantz CD4000 modifying..


am realy a vinyl guy..
and seldom plays cd.. for the experience.

now.. i got a Marantz CD4000 laying around..
and thought i would be a nice project to upgrade it.

this is a real cheapo player.. but was popular in it`s time..
due to the VAM1201 transport.. that will read anything..
(maybe bar-code`s to.. )

but the components used.. am not that certain of..

The DAC is a constant calibration type TDA 1545
digital filtering = SAA 7378
Low pass filtering & output = one NJM 4560 dual op amp.

and there`s also the psu.

anyone a service manual for it..
or have some ideas about changing critical components. ?
