ciao..
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. ?
