I picked one of these up for a fiver, recently - no remote control, and it looked like the playing of cd's was in the charge of a 6 month old rusk eater at din-din time, but I was pleasantly surprised by what I got. Playback is spacious and detailed, but a little bright, and it handles most music well, if as I said a teensy bit light in the bass department compared to flac-7520-preamp playback of music. It didn't skip a beat on any of the CD's played, the only detrimental thing I can say about this CD player is that the drawer operation is somewhat jerky. That, and the buttons are all in French. Mon Dieu...

Since I only spent a fiver to get what has the potential to be a rather good player, I think I'll have a bit of a play with this wee beastie.

Step one is to get that drawer mechanism fixed and a general check-over - so it's gone in for a service to Peter Ellison in Cardiff. Should be a cost of about £45.

Step two is going to be to do a deep clean on the unit - (it got a quick wipe before it went to Peter, but I'm going to "valet" the unit).

After that? Well, after that is where I could do with some advice. Here's what I'm thinking of doing:

1) damping the internals - the case, being plastic, is somewhat lightweight. Butyl/aluminium sheet is available quite cheaply, as is sorbothane sheet. Cost about £12

2) To continue with the damping theme, sorbothane feet. Cost £15-20

3) Upgrade the master clock in the player to improve reproduction (this seems to improve bass in particular). Cost £120 upwards from what I've seen

4) Upgrade the power supply/supply the master clock with a separate power supply. Costs I've seen are from £40ish upwards

5) General refurbishment - respray the metal lid, polish the gloss plastics back to lessen the impact of a couple of minor blemishes, possibly respray the plastic sides to give an exact match to the lid, and if a defunct Phillips CD 350 comes up at the right price/time, swap the French Buttons for English ones. Polishing gloss plastics costs whatever Brasso costs these days. For respraying, it's the cost of a can of etch primer (as I'd be painting plastic this is essential) plus the main coat colour - about £15 for decent stuff, possibly plus lacquer. Dead CD player cost? varies :D

Any thoughts on other useful modifications would be gratefully received. Recommendations for sources of things like clock/psu would be of interest as well, particularly if you have experience of the items in question.

I should have said - probably going to run this through the digi output to my dac/pre, but would also be interested in peoples' experience of op-amp upgrade modules.

I'd say op amps/ caps will make a big difference but probably not as you're going into a dac and I'd hope the digital output bypassed all these?

Yes, if I go the DAC route changing the op-amp won't make any difference at all - it gets bypassed. I still have the option of using the CD's output stage, and am considering options at this point. The vibration damping upgrades are pretty much a no brainer, due to the lightness of the unit and its' largely plastic construction - and their low cost. The other stuff is all up for debate.

I now have TWO of these players - once they're both repaired/serviced, I'll be in the fortunate position of being able to directly compare the effect of upgrades. Fun times (and no doubt some frustration) ahead!
