Certainly. All caps have been replaced with new, higher value, higher quality caps from Sanyo Oscons and audio from Elna, especially at the digital filter and supply for the DAC itself. The diodes in the main power supply have been replaced with ultra fast diodes. The op amps in the output stage have been upgraded with chips from Analog Devices, and these have been biased further into class A.
Hi guys, nice Video. I actually caught such an exemplar in quite good condition. Anyway all capacitors shall be replaced according to your recommendations. What I didn´t copmpletely understand is the item with the 3,9 k resistor at the AD 712. Can you possibly specify a litte bit more (between which Pins)? Greetings from Germany
Congratulations on your find. It's a very nice player. I will get back to you with the information on biasing the op amps when I next see my dad. Thanks.
I wish I had a picture of a Marantz CD player my dad modded a while back. Every aspect of the player, from the transport motor, laser, sled, the dac, the output stage, had its own linear transformer power supply. The op amps each had a 300VA torroid powering them. It blew my mind at the time. It was a primacy experience in my journey as an audiophile.
@@mydadsaysaudio6192 impressive! The most I have done myself is replace the laser mechanism on my old Marantz Cd 63 mk ii ki signature edition cd player. Wasn't as hard as I thought it was going to be. I still have it in a second system but much prefer my Audiolab CDQ 8200 in my main system.

Hi guys, I have one of these presently not working (tries to read cd, but fails with a data error). Do you do repairs or can you recommend a repairer,. I am based in Melb/Aust.
Any chance you would be willing to share the full list of mods?

Oh, and he added a shielded mains cable and oriented the mains transformer for the smallest field.
Wish i had i dad like yours he could mod my Philips cd650 !
I feel lucky to have such a cool dad. He's working on some of my gear at the moment.
