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.

Antique Electronic Supply at http://www.tubesandmore.com/ sells multi-section
electrolytics. They're a bit pricey, though. Make sure that your credit is in
good shape.
