Restoring Sansui Dynamic Oval Capacitors

Finally I got all what I needed for that job so, I wish to share my experience with you guys...

First picture, about what I am talking here :D

This is the picture of big oval capacitors what Sansui installed in top of line products in late 70ties (like G9000 receiver, AU919 amplifier...).
That kind of capacitors you cannot buy now-days, Nippon Chemicon has one (I saw it in theirs catalog) but I didnt find it in any web store...
So, I must restore it....

Scott, you asked me about new Nippon oval capacitors...now, I am not at my home, and that datasheet is at my home computer, so I can show you that info at Friday when I will be at my home...
 
So I see the caps are 80 volts, how many uf is each of the 8 caps? Can I ask what size that heat-shrink is?

There are two Panasonic 10000uF/80V capacitors in every oval capacitor. The heat-shrink what I used for that job has 100mm diameter, and it is big for that, but the good thing is what its shrink ratio is 1:4.
 
Very nice work as usual Kale and great pictures. CDfixer has a similar process. He did a thread on it awhile back.
