I need ideas on a can capacitor

[mustang guy]

This is a little bit of a dilemma. I need to find a 1000/1000uf 25v can capacitor that is exactly 35mm wide and 50mm tall. The reason it has to be exactly that size is the AM antenna of the tuner I am working on mounts to it, and it has to be this exact size. The part numbers I have found are:

Cornell-Dubliier A0130
Mallory WP201.15
Sprague R2619

I have looked everywhere and am coming up with nothing. The old cap is completely bad. I have thought about hollowing it out and inserting a cap up inside the can and having the other cap below the can.

Any help would be appreciated.

I would leave the old can in place and mount both new caps under the can if you have enough space in the chassis. I can be a lot of work to hollow those old cans out.

1000 uF, 25 V doesn't take up much room these days. I looked at some 1000 uF, 50 V rated for operation at 105 C for 5000 hours. Even those were only 16 mm in diameter and maybe 25 mm tall. You should be able to find a radial type that'll fit in the chassis without too much trouble. Leave the old can in there for mechanical support of the AM antenna, but disconnect it. Just in case it decides to short out and explode...

I agree with both posts on leaving the can in place and mount new caps elsewhere, that is usually what I do if there is enough room. I have gutted and stuffed old multi section cans before and it's a neat trick but as stated it can be a pain and it's also more time consuming.

Thanks for the responses! I yanked the can out already. It is dripping oil, so I am going to carefully hollow it out and re-install it as an AM antenna mount.

Why not fabricate a new antenna mount out of something like a piece of tubing, then the new cap's size would be irrelevant.

The tuner is museum quality, and I really want to keep it looking that way.

Just be aware of the nasty chemicals that may be lurking inside that can. Once you have emptied the can then do as our oriental friends do and make a fake using the old can.

OK, thanks. Good advice.

Way too much bandwidth wasted on discussing such a piece of junk like that...
Just kidding...good advice all around, and that tuner is immaculate, absolutely beautiful.
Thanks for sharing the photo and keeping the unit in excellent shape.

I about fell over when I started reading that. LOL

Thanks. BTW, I have hollowed the cap out and re-installed with antenna. It was a pain!

I'd be interested in more pictures. It looks like a nice piece of kit...

I took these pictures when I first received the tuner and before cleaning. There wasn't much to do!

Wow. Really, really nice.

So it's not "just" a tuner. I realize that it is a mono unit, but have you tried the phono section?

BTW, congrats on the cap mod.

 

[mustang guy]

No I haven't. I also have an 80T tuner (preamp) that I actually like a little better. Go figure...

I am currently listening to my Fisher KM-60. Sounds wonderful! And looks as good as it sounds.

Here is a picture before restoration:

It cleaned up nicely. The brass on the knobs and the rear top vent look shiny and new now. I also replaced all the foam behind the glass, and added foam so the lights wouldn't show between the chassis and the case at the top. It's now 200% better looking than this pic.
