Wanted: multi-section cans
 
1 Attachment(s)
One 2" high and one 4" high, both about 1.5" at the base. Pretty standard diameter I think. The smaller one had three terminals, the other 2 at opposite ends. Doesn't matter if they're heavily used or NOS, but I would prefer those with markings I can get rid of altogether.

One day I'll learn to gut these neatly, hopefully this time.

Tip: saw the tops off just above the place it narrows above the base, use a fine drill bit to make holes through the wafer for the leads, install the new caps, yank guts out of old can top with cork screw, place old top over new caps tape cut up with metal backed ducT tape (not rubber based ducK tape), and it will look professional and be less work.

I used to uncrimp the bottoms, but cut my self too many times doing that, and was unsatisfied with the average quality of the results....

If it's a 70s-era Sprague, I use the method Doug Harmon chronicled:

It doesn't work on Mallory or CDE cans - gotta to either the drill-baby-drill, or Tom's saw-it-off-above-the-neck trick.

I was thinking of just having someone with a lathe cut enough off the base to release the contents, then hot-glue the top in place afterward. One thing I was successful with in my latest attempt was soldering the leads above the wafer board, after drilling 1/16" holes in them. A little bending of the terminals, cutting out a little rubber for clearance, drilling the proper size holes and applying enough solder should ensure the connections inside don't break.

By the way, I no longer have the cans in the photo so I need replacements.

Still need a set, those I got aren't really suitable for my project. For instance one's 1/2" too tall. The Mallory FP cans with the "T" style lugs would be ideal. One about 2" high, one about 4" high, both about 1.5" at the base, at least 3 lugs on the smaller one, at least two on the bigger one.

Edit: All set now.
