How I Re-Stuffed Sansui Eight Main Caps

[rd48sec]

Working on a restoration/re-cap of a Sansui Eight for a client. Since the main caps are such a large diameter, I wanted to re-stuff them with slightly larger and higher voltage caps (8200uF, 80V, 105C).

At my regular place of work we have a small machine shop which includes a lathe. I chucked the cap on the lathe and with a clamped dremel, I cut the cap open. I then removed the old cap. Drilled a couple holes for the leads of the new cap ( I had to extend the leads with buss wire). I used hot melt adhesive to hold the new cap in place, and soldered the new leads to the old leads. A strip of aluminum tape to hold the two pieces together. Once the clamp is in place, it is like nothing ever happened.

Looks great.
I’ve never seen anyone stuff any cap that was covered in the heat shrink wrap before. Only the old aluminum cans seem to be restuffed. You may be setting a new trend.

Beautiful work. Nice to have that huge lathe as a helper!

Awesome job. Only problem is, now you can't see if the new caps start to leak.
