Multi-Section Capacitor "Empties"

Are you asking for the parts to build a multi section air variable capacitor? Mikek

Mikek:

I am looking for the can and phenolic wafer to stuff my own multi-section electrolytic caps.

Thanks!

Hi there,

I recently came across these:

on e-Bay and ordered a few that have not arrived yet. In my case I've got a 4 section cap: 330-100-100-100 all at 75 volts, Oh, and the case is POSITIVE as it is for the bias supply in the amp.

Both my customer and I are OK with the look of it, and soon I'll see if it works. I like that they have the option of grounding to the chassis or not.

Those are handy, but don't provide the "look" of the original can.

I restuff all the can electros I run across - not for originality as much a s for maintaining the original layout. Some folks leave the cans in place, disconnect the wiring, and add terminals to the bottom. This takes up a l ot of room.

I restored a 1951 Andrea TV a few months ago and restuffed all the cans. I believe there were 7, maybe 8. Adding terminal strips and two to four mor e caps to replace each can would have been a nightmare to the guy in 50 yea rs who wants to repair or restore this TV again. Since this model was cove red by Sams, the bottom of the Andrea still looks like the photofact pics.

If I had to, I'd use the wafer you linked and try to use a plastic or cardb oard tube over the caps just to make them look at least a little vintage.

I didn't have any luck finding aluminum cans or shells. The first few photos might be worth following: The sources seem to be only in China or India and only sell in large quantities. The few capacitor rebuilds I've done were all in the original can. Good luck.

electrolytic caps.

If you're not trying to exactly duplicate an original can, you can always u se 1.25" PVC pipe which will be just a wee larger OD than the original stan dard size can. Cut it to fit, place it on end over wax paper, fill will *l ong* set epoxy to form a cap at the end, then sand and paint a flat silver.

Hot glue or fast epoxy the PVC "can" down over the new caps on the wafer li nked elsewhere in this thread. It won't look exactly like the original can but it will be better than using exposed modern electros on the new wafer.

are you going into production of fake capacitors :-P

Uh, no. I am hoping to find a simple kit to do a passable replacement. Fail ing that, I will simply purchase the mounting plates and leave the individu al caps exposed. Thanks, all for the various pointers. I have found the usu al suspects on my own, and I do own a large tubing cutter, and so forth. Bu t, I was hoping that someone out there made 'empties' as a kit.

Thanks again!

Nice job! Can says 6800MFD/50VDC and the cap inside is

How about these cans?

Looks like 2.1" is the highest they get. Not a lot of room for multi secti on requirements, and they're probably expensive unless you order 1K or more .

I kind of like my idea of using schedule 40 PVC. Cut to any height, easy t o shape or round off the edges, spray with flat gray or dark silver, hot gl ue over new caps - done. Cheap and easy.

I would lighter weight PVC - schedule 40 is kinda clunky in this use. PVC sink tail pieces (1-1/4 or 1-1/2").

Even better.
