Sony CDP 337 ESD cd player

[Holte Ender]

I am selling my Sony CDP 337 ESD CD player.
Gloss black finish.
Condition 9/10.
This unit contains the KSS190a laser mechanism and a TDA 1541 DAC, two of the best designs ever made.
Heavyweight high quality build.
Excellent sound quality.
The player has been serviced and restored with upgraded parts by Elna, Wima, Oscon and Panasonic FM.
Remote control and Sony manual included.
Looking for £450.
I can arrange an insured courier, meet-up or demonstration/collection in Gloucestershire.

Here are full details of the work I did:

Strip down tray loading mech. Clean off old grease from all moving parts and rebuild with fresh grease and new tray loading belts.
Turntable motor bearings cleaned and re-lubricated.
Laser head guide rail cleaned and lubricated.
Laser optics cleaned.
Laser Focus bias adjusted.
EF Balance adjusted.
PLL frequency adjusted
Focus gain and tracking gain adjusted.
Worn-out turntable motor lower bearing/thrust pad repaired with 0.5mm thick PTFE disc.
+5v voltage regulator for digital filter upgraded to ultra-low noise regulator.
Output DC blocking coupling caps upgraded to Panasonic metalized polypropylene film types.
Power supply decoupling capacitors for DAC chip -15v supply upgraded to Elna Silmic with additional X7R ceramic bypasses.
Power supply decoupling capacitors for TDA1541 DAC’s +5 and -5 supplies upgraded to Elna Silmic.
Power supply decoupling capacitors for opamps upgraded to Elna Silmic
Power supply decoupling capacitors for digital filter etc upgraded to Panasonic FM and Sanyo Oscon with additional ceramic bypasses.
Ferrite beads added on +10v supply that is shared between digital filter and DACs.
This particular player gave one the the best/cleanest RF eye-patterns I have ever seen, which is testimony to the sheer excellence of the KSS-190a laser mech. They don't make 'em like this anymore!

Price reduced to £425.
I will have to put it up for auction if there is no interest.
