Do they still sell Aluminum Electrolytics

Do they still sell the Aluminum Electrolytic Cans?

I am referring to the old ones that were used on all the old tube equipment and would have 2 3 or 4 caps in one can?

Such as

30mf 600V 20mf 450V 80mf 300V 50mf 200V

I dont see these advertised anymore, and old ones, even if not used, seem to have gone bad from age.

If they are not available, what are restorers using? Sometimes there just is not enough room under tha chassis for multiple single caps, and a person can't just solder to the terminals on the dead caps, so terminal strips are required. Plus it just takes away from the "original" look.

I have this fascination with old tube equipment. Guess it just takes me back to my childhood when my toys were old radios and tvs that other people threw away. There's just something about the look of the components both on top and under the chassis that modern printed circuits can not match. The problem is getting parts !!!!

A lot of restuffing of old axial tubular caps , with modern innards, goes on , do they do the same for canned multicaps? Modern replacements always seem to be less volume, so no problem there. As long as the cans are not totally sealed again, with new innards, is there a problem? can they be opened and cleaned out cleanly in the first place? Not something I've tried

Sure, I restuff can [FP} type electrolytics quite often. There are procedures given at several information sites. My prefered method [that works in situ quite often] is to use a Zona razor saw to cut the can off about 3mm [1/8"] above the bottom ring and pull the can off along with the 'guts'. Reach through the gap and snip the ribbons that connect the cap roll to the terminal plate. Heat the can to soften the tar 'glue' and pull the slug out. Wash out the can and swab the base clean. From the bottom, drill a wire sized hole through the insulating plate close to each terminal pin and close to one of the ground tabs. Assemble the new caps into a bunch that will fit and with the leads in the proper places, then stand this in the base with the leads poked through the holes, wrap with long life insulation [I use insulating paper]. Finally, make a ring of plastic [I use PVC] about 6-8mm wide to fit inside the can behind the joint and finally apply epoxy to the outside of the ring then fit the can back on. Solder the leads to the terminals on the bottom. The razor saw cut is so fine it is pretty much invisible.

sells multi-section electrolytics. They're a bit pricey, though. Make sure that your credit is in good shape.
