Nec Super CdRom2 audio problem (maybe a cap)

[raggio252000]

Hi!

I bought an old nec cdrom2.
The system works great, however I have an issue with the audio, the sound is not loud but after playing around 15-20 minutes the sound become normal, I think that it's a cap/s like the other Nec machine as the GT model but I don't where is the audio section on this console. Anyone know where I can find it?

I did some pics of my system:

Welcome aboard.

I'd do a complete re-cap while you have it open.  Some caps are already failing, and if you wait for other symptoms to appear for other areas in need of help, it might be too late.
