I'm looking for the above mentioned electrolytic cap to restore a
Hallicrafters S-53A receiver. Its an aluminum can (twist tab mounting),
1 3/8" dia, 3" tall.

I know quad section caps at 350 V are rare, so I'll settle for the
one with first three sections.

Also, The measured voltage is only about 250 volts, so perhaps a 300
volt cap would work. What do you think?  Thanks.

^^^^^^^^^^^^^^^^^^^^^^
I think NO!
If 250V is the DC voltage on the caps the peak voltage is:
250 X square root(2) = 350V
hope this help.

...
Yeah, nobody is making these things anymore.  I did see a blurb in
rec.antiques.radio+phone a while back that there are one or two custom
rebuilders who will put new elements in your old can.  Maybe someone can
come up with the name (maybe try Yahoo or Alta Vista for capacitor
rebuilders?)
