Att: All Tech Gurus! This Marantz CD32 sounds great as it is really but it was built in about the 1980s or thereabouts and I want to know if I can upgrade the chips in it seeing as how the technology has advanced so much since then, this Marantz already has a beautifully smooth transport and any upgrades that could be done would only do it justice.

Fairly sure I've posted most of the same info on a thread here a few years ago but couldnt find it now

I cant upload the service manual but you can get it from Hi Fi engine.com.
An SMD would be too much of a hassle to install. There must be a better Op Amp available nowadays that fits straight in? But which one?
Which op-amp in the circuit would the Muse 8820 replace? I've been trying to work it out myself by comparing datasheets, etc but it's beyond me?
I checked them out and yeah that's the go. I didn't know there was such a thing? Thanks mate.
I'll try them and see how they go, I'm not sure that I will be able to hear much of a difference though but if you could hear a difference, then maybe I can too? I'm 64y/o and I can hear up to 12,000htz. Anything that goes towards refining the final sound output is OK by me. I'm going to do the power supply if I can get the add-on for my Firefox browser to make Photobucket work? All the photos and diagrams are in there! I contacted Photobucket about this 3 days ago by email, still waiting for a reply!
CD52 Mk2 SE
You will find a manual at:

I have a query
I have replaced the tray opening gear wheel and belt on CD52 Mk2 SE.
My tray attempts to open but falters.
I have checked the action. As part of the opening action, there is a ramp on the CD tray which lifts the 'Disc hold down' mechanism which is spring loaded down on the tray, A pair of rollers run on the disc hold down unit run on this ramp. My tray almost gets to the top of the ramp and then stops. The motor and belt stop, and do not appear to slip.
If I give the operation a slight assist by reducing the weight of the spring loaded hold down mechanism, it functions perfectly.
My query: Is there a way to reduce the load on the tray motor, or beef up the motor?
