Venus orbits the Sun 13 times for every 8 Earth orbits. If you track the relative positions of Earth and Venus over an 8 year period, this is the resulting pattern.

How to repair a Sony WM-D6C
I found a Sony WM-D6C First Revision in the garbage can. For those not knowing it, it is worth about 150EUR or even more (depends on condition). But mine was broken, the speed was screwed, it was playing way too fast, so something was wrong. So I read up on that walkman and found that one of the ICs, which regulates the speed, is broken.
Its the Sony CX20084 SOP 16. So I went to ebay, ordered 2 (1 backup) from Hongkong (in total 5eur with shipping)
So you remove 4 screws from the bottom and then you see this. Problem is that there are many cables blocking the way so I just temporarily desoldered some (the ones I marked pink) and then taped the rest to have space to work with the IC. Tip: use some pin to push up the legs a bit while desoldering. If you done then just install the new IC (have fun :D )
After I had the new IC in place it worked flawless.
