[Hallicrafters] Which cap to replace molded paper

[Bill Gerhold]

Bill,

If you plan on restoring more radios than the one you are currently working
on, you might want to purchase a capacitor kit.  Go to this site, they have
packages (kits) that include the most used capacitors in tube radios and I
believe they are all rated at 600vdc.

Subject: [Hallicrafters] Which cap to replace molded paper

I appreciate the guidance all have given me as I step into the world of
boatanchor restoration. I thought I'd share a short study that I just made.

I need to replace my molded paper caps and am bewildered by the choices. I
decided to do a type-by-type comparison to help highlight the differences
between n caps and their relative costs. All the replacements need to be
600v or above (some 630v).   As an example to compare, I will compare .1mfd
caps. 

I have the following choices from Antique Electroinic Supply
(www.tubesandmore.com)  :

Mallory        Tubular metalized polyester            10%    Axial Self
healing    $1.05
Orange Drop 715p series    Polypropylene film    5%
$1.22
                    716p series    polypropylene film and foil 10%
$1.84
                    PS series    polyester film            10%
$1.42
Lolen Fast Metalized Polypropylene              tolerance not given
$1.85     
(no name) Metal film Tubular    Non-inductive self healing windings     10%
$0.66

It looks like a choice between the Mallory and the no-name metalized
film/polyester caps. they are both self healing (does that help?)  I guess
the next question is whether the name brand "Mallory" is worth 39 cents.
Or, if I go with Orange Drop 715p, is 5% better tolerance woth another
17cents.

What do you guys use? Keep in mind this is to replace molded paper, nothing
more exotic.

Thanks,
