Re CD32 Audio noises problem

Hi

I have a working CD32, however I am getting a lot of crackle and interference type noises from the audio out.

I ahve replaced the 2 associated CAPS but want to change the associated transistors.

I am unable to identify them.
Can anyone help please.

Hope they are not too difficult to source.

Looked everywhere for a complete list of CD32 Mobo components but can`t find one.

Thanks

You need to rule out the cd mech. As you could be looking for a board fault and it could be the mech.
With out hearing it, I could'nt tell you if its a cap related problem or mech.

Hi

It definately is not the CD mechanism.

I am looking for a board fault.

2 CAPS were replaced on the audio circuit, however the transistor associated with the sound chip can`t be identified as the markings have `worn` off.

This is what I need help with

PLUS a component list for the CD32

Thanks

Do a search on google for Amiga CD32 schematic diagram. You should find a manual.

Hi Calibra,

I've uploaded CD32 Rev.3 and Rev.4 mobo and FMV schematics to The Zone for you.
