Well. I recently acquired with some luck a Sony D-99 (in non working condition), for free. And a D-303 for 30 dollars (in working condition). Both in pristine cosmetically condition. Didn't know that they were this collectible until I started looking them up. I just have a soft spot for these metal build vintage machines, and I wanted a discman again
D-99:
I got the D-99 working again. Just for helping other people out: The laser sled was stuck in position. It just made sounds moving the laser up and down but it did'n read a disc. When I tried to start the laser-assembly from the back position. It didn't move to the centre when I started the player with a disc. By pulling the smallest gear (the one from the motor) backward - out of line with the other gears - I could slowly get the other gears moving. But they were really stuck very hard. Once they were free again I regreased them and the player worked.
Sound was very silent and distorted (on both line-out and headphone out). So I recapped the caps for the these two outputs. They were also the ones that were in bad shape (leaking and bulging form the bottom). Now it sounds like new and pretty good. I was quite impressed hearing my cd's like this. Very good separation and clarity.
D-303:
This one has the skipping problem. But after reading SirNicks hinge-repair... I remembered my closing cover is not closing perfectly horizontal. So i will also get of the cover and look if something is bend there. The motor I have does not feel to have much play when i try to move the disc platter sideways. And so I don't think think the motor is very worn out. So I don't know if replacing the motor is gonna fix it. I was thinking of also lubricating the motor shafts but I don't know how to do this. Do I have to take the spindle cd-platter off? There are two screws underneath the spindle platter... Do I loosen these? But then I still have to get the platter from the motor shaft... Is this just clamped on the shaft from the motor?
Another thing I was thinking of for the skipping problem is the way the laser assembly is put on a separate part connected with rubber and springs to the main chassis. The rubber from these shock absorbers looks worn out. Does anybody know where to get new rubber shocks for this player? I was also thinking of stretching the springs a little bit so the assembly sits a little higher in the chassis...
I also replaced two of the caps because I also got distorted sound from the headphone and line-out. But I want to redo them properly and check for other caps that have gone bad... Or just replace them all
It's fun working on these players and rewarding also. The D-99 sounds so good. I guess it's a sacrilege to say but at the moment I like it better than the 303-sound...
Looking forward to hear your replies!
Best regards,
Simon
