Dead Marantz CD-63 KI

[Griffymark]

I modded this CD player a few months ago with a Net-Audio Rock Clock, and was very impressed with the improvement in the sound.

Then last week the player died a death. The transformer does not appear to power up - no humming sound and it stays cold. I have tried changing the two internal fuses, and an alternative power lead, and have confirmed that the plug fuse is not blown......to no effect.

On modding that player, I did short-circuit two leads coming from the transformer, but fixed the problem, and the machine continued working.

But no more.....

Anyone had this before? Does anyone have the service manual in PDF?

Thanks in advance.

check any fusible resistors in the circuit board. Often a blown flusible resistor remains intact. fusible resistors often have a fifth band (sometimes white in colour) and are usually raised off the circuit board. My 2¢

Do a search here, there should be a link to the service manual...it's 9 megs
good luck

Thanks for the replies. I found the service manual eventually, and will check out the resistor as recommended.

Hi ,
Check the transformer for secondary voltage present. If not check if primary voltage (mains) is present.
My best guess: the transformer has a built in fuse that is blown.

The transformer of the CD63 has a (unfortunatly non-replacable)built in thermal fuse. This could have heated up a lot when you made the short circuit but just not enough to blow it instantly. Check the voltages on the output of the transformer.
