Default Bringing back to life old vertical cd-player

Hi Everyone,

I have an old Technics SL-P10 at home. At the moment it's only as a "visual element" on top of my audio rack.


During past weeks I have been wondering, if it's possible to bring it back to life.

Its laser has been dead for years and replacement laser or optical pickup is no longer available
.

echnical description:

Sampling frequency 44.1kHz
Error correcting system Technics super decoding algorithm
DA conversion 16-bit linear line
Frequency characteristic 4Hz - 20kHz
Dynamic range 90dB or more
SN ratio 90dB or more
THD 0.004% or less (1kHz, 0dB)
Channel separation 90dB or more
Wow and flutter Quartz-crystal precision
Laser Ssheme Astigma 3 beam
Light source Semiconductor laser
Wavelength 800nm
Output voltage A 150mV (-20dB) variable
Power source AC100V, 50Hz/60Hz


I have been wondering about 3 options:
  • to replace the laser with some random 780nm laser
  • to replace the optical pickup with Sony KSS213
  • to replace the whole transport with Philips CD-Pro2
So now I turn to you about some ideas. What would be the most realistic way to get my vintage cd-player back to operational conditon?

Option 1 is out of question. What is the type of the original optical pickup?

Yes, most likely option one is not the easiest way.
SL-P10 uses one of a kind pickup SRUD010N01Z which looks like this:

If you really want to have this cd player working again, your best and most cost-effective way is to simply buy another, even if it is a parts unit. Try Ebay or Craigslist.

Good luck

SL-P10 is know for it's unreliable laser. So there will be a problem with buying another similar player for spares, because sooner or later that laser will also die.
I guess I'm willing to spend upto 500€ on that project, but before buying any parts I want to be sure that salvaging my cd-player is possible.
