I admire your handiwork Erik, well done on the progress so far. Actually it is a valuable lesson for us all - just keep at something and you will get it done....



Speaking of which I jerry-rigged up my shigaclone tonight and yes, it plays! Sounds not too bad either. I have only removed a few parts and used a quick and dirty PS. i had only 90R and 330R so they went in for the SPDIF.


Now to another question: What was the end result of the experiments with the different platters people made/bought? First thing I noticed when I put on the first CD was how much it was out of true. Did the fella in hong kong (?) that was making the screw down puck sort out the out-of-round issues?

Put mine into a quick test rig yesterday, nothing modded and just a couple of 75r resistors on the output.

Sounds decent but will definitely need the mods and a stable case to bring the performance levels up.

As the poster above i'm finding the cd has a fair bit of 'wobble'. Some of this is just a trick on the eyes from the cd printing being slightly off center. I definitely think that a proper screw clamp is needed, at elast for my setup anyway.

Out of curiosity woodturner-fran did you use a 31 or 51 model?

I gave up on the platters I bought (the mechanism could not reliably read disks with either of the ones I was sent due to wobble and eccentricities) and went back to the stock set up. I had several to choose from and just found the combination that ran most true. I have a few recently purchased cds which are warped - no standard clamp is going to fix this.

Using a screw on clamp without some way to clamp the lower half of the platter so that it does not turn is a royal p*i*t*a..

Personally I think one of the cdrom ball clamps is a better bet and eventually I will procure one of those.

Sorry to hear..but on the other side loads of top cdplayers use magnetic devices...

Today I took care of building a front support with two adjustable feet ...I use ebony...but that may come as no surprise by now...

I drilled a hole for the brass left and right inserts with thread for screwing the feet in place and being able to level the transport later on......

It is rather a secure job to get the 3 feet exactly on the 3 stands...but that will pay off later on....
