Default Marantz cd 273 schematic.

Hi

I have Marantz cd 273 and Id to upgrade it. Does somebody have the Schematic?

Dac chip is a TDA1541 without A and without 14 decoupling caps. Should I add decoupling caps to TDA1541.

Thanks

The caps will be surface mounted on the other side of the pcb to the TDA1541.

Take the circuit board out and look on the other side - the decoupling caps will be there!

You are right

How to upgrade my cdp without a schematic? Has Philips an equivalent Marantz 273 model?


PS: many time ago I made a NOS mod.

Thanks Andy.





Question?

Is it true? Or TDA1541 (without A) has internal pins 16 and 17 connected by a cap?

The TDA1541 and TDA1541A are not identical and cannot be substituted. (as the post refered to says)



I have a CD273 SE with a TDA1541 S !!
